Cutlines, another name for photo captions, are a few lines of text that provide context or additional information for published images. In some circumstances, captions and cutlines are distinct from one another. A caption is a brief (often one-line) title or explanation for the picture, whereas a cutline is a longer, prose block that describes the picture more thoroughly, provides context, or connects it to the article.

The first things people read in a publication are frequently the photo captions. A crucial component of a news photographer’s job is writing captions for photos. The reader should receive the essential information from a photo caption in order to comprehend the image and its news value.

Caption writing should adhere to the same professional standards of clarity, accuracy, and completeness as any other writing that appears in a publication. A lousy caption can lessen the impact of a beautiful photo and damage the caption’s reputation as journalism by being uninformative or, worse, misleading. Why should readers believe the rest of the publication if they can’t trust the accuracy of the straightforward information in a caption?

Use of modern reproductive biotechnologies or assisted reproductive techniques (ART) include in general artificial insemination, embryo transfer/sexing, in vitro fertilization, gamete/embryo micromanipulation, semen sexing, genome resource banking, and somatic cell nuclear transfer (cloning) in conservation programs for endangered mammalian species. The biotechnologies of these kinds generally permit more and more offspring to be obtained from selected parents to ensure genetic diversity and may reduce the interval between generations.

In order to get assured supply of quality seed weaned on formulated diet, the captive spawning is the right choice for successful farming of striped murrel. Captive spawning involves several activities such as broodstock development, induced breeding, hatching of eggs, larval rearing, etc. These activities are given in detail in the following sections.

4.1 Broodstock Development

Brood stock development is an integral part of captive breeding programme in fish and the success of breeding largely depend on it. It involves rearing of healthy brooders of both sexes in captive conditions to meet the targeted production of seed. In striped murrel, maturation of gonad begins in the first year of their life. However, brooders of 2⁺ year age or above are better and recommended for captive breeding (Pati et al., 2004). A size of 400g to 1500g is considered ideal (Fig. 10). Brooders may be procured from wild sources or reared on-farm from farm-raised fingerling. Brooders from wild stocks are to be procured at least 2-3 months prior to spawning season so that they acclimatize to the farm conditions. It is recommended to give them a bath of 50 ppm formalin for about 8 hours under vigorous aeration before stocking in the tank/pond. Formalin treatment removes external pathogens from the fish body. Brooders raised at the same farm do not require formalin treatment, if they are free from any wound.

The carambola, Averrhoa carambola L., is believed to have originated in Malaysia and the Molucca but it has been cultivated in southeast Asia for many centuries. It belongs to the family Oxalidaceae. The carambola, Averrhoa carambola L., is usually called balimbing, belimbing, or belimbing manis (“sweet belimbing”), to distinguish it from the bilimbi or belimbing asam, A. bilimbi L. In Ceylon and India, the carambola has the alternate names of kamaranga, kamruk, or other variants of the native kamrakh.

Cultivars/Varieties: Sweet and sour forms are recognized a cultivar in India. In countries like Australia, Japan, Taiwan and, USA named cultivars are grown.

Uses

Fruits are mainly used for dessert purpose. Slightly unripe fruits are used for jelly and pickle. Unripe fruit is also used for dying as it contains potassium oxalate. It is a popular substitute for tamarind in cooking. The acid types of carambola have been used to clean and polish metal, especially brass, as they dissolve tarnish and rust. The juice will also bleach rust stains from white cloth. Unripe fruits are used in place of a conventional mordant in dyeing. Carambola wood is white, becoming reddish with age; close-grained, medium-hard. It has been utilized for construction and furniture.

Carambola or starfruit is native to Indonesia. The fruit has ridges running down its sides (usually five) which in cross-section resembles a star, hence its also known as starfruit. It has a waxy, golden yellow to green coloured skin with a complicated flavour combination that includes plums, pineapples and lemons. Carambola consists of two main types of varieties viz.  sour and sweet. The sour types contain as much as 1 per cent acid and the sweet types have low acid (0.4 per cent) content with 5 per cent sugars.

Genus : Averrhoa 
Species : carambola L.
Family : Oxalidaceae
Chromosome No. : 2n= 22, 24

According to a Dutch traveller Linschoten (1598) has described carambola as a ‘fruit with eight distinct corners as big as a small apple, sour in taste, resembles an unripe plum. The Chinese and Hindus eat this fruit as vegetable when green and as a fruit (dessert) when ripe. Carambola is esteemed in the Orient and is wide spread in the tropics. The bilimbi is a close relative to Carambola and in every livelihood is native of Malayan region and is considered as the only cultivated species. The fruit is very acidic in taste, and in appearance resemble cucumber.

Carambola (Averrhoa carambola) is a fruit of warm tropical and sub- tropical areas of the world. The fruit is oblong with three to six longitudinal ribs, resulting in a star shaped cross section when cut. Usually they have five ribs which give rise to common name of ‘five corners’ or ‘star fruit’. The tree is medium-sized, attractive and evergreen growing to about 10m. The fruit has emerged as an interesting addition to the table fruit, not only as fresh fruit, but also for its juice, decorative uses and sherbet qualities.

Description and Distribution
Under the Prevention of Food Adulteration Act (PFA) of the Government of India (amended upto 31 March 1996) both Caraway (Carum carvi Linn.) and Black caraway (Carum bulbocastanum W.Koch) have been described in Hindi (Indian language), as “Siah zira” or “Kala zir””. These two species have similar cultural requirements and are thus covered under one head
Caraway
About 2000 years ago, Roman soldiers dispersed Caraway seed from it’s home in Asia Minor to most of known countries of the world. North Europeans and central Europeans, especially the British and Germans, respectively, have been using it since centuries. In India, also, it is being used since long. Caraway or Caraway seed of commerce is the fruit of a biennial herb. It is a native of North and Central Europe, and is extensively cultivated in Holland, Poland, Russia, Bulgaria, Denmark, Syria, Morocco and to a small extent in England. It has been introduced into the USA, where it is grown as a garden crop. It (Black Caraway or Kala zira) grows wild in India in the north Himalayan regions. It is also cultivated in the Indian plains. It is also cultivated as a cold season crop in the hills of Kashmir and Kumaon at an altitude of 2740 – 3660 meter above mean sea level, as a summer crop. The Caraway plant usually has a fleshy root and a slender branched stem, that attains a height of 0.5-0.6 meter. The compound pinnate leaves are divided into very narrow segments, the small white flowers are borne in fleet, compound umbels; the fruit, when ripe, splits into narrow, elongated carpels. A fruit is 4-6.5mm long and curved, pointed at the ends, and with 5 longitudinal ridges

The typical Carbo patient is sluggish, fat and lazy and has a tendency to have chronic complaints. Blood seems to stagnate in thq capillaries, causing blueness, coldness and ecchymosis. Body becomes blue icy-cold. Bacteria find a rich soil in the nearly lifeless blood stream and sepsis and typhoidal state ensues. Weakness due to excessive diarrhoea, menstruation or other debilitating diseases. The patient may be almost lifeless, but the head is not, coldness, breathe cool, pulse imperceptible, oppressed and quickened respiration and must have air, must be fanned hard, must have all the windows open. The patient faints easily, are worn out must have fresh air. Haemorrhages from any mucous surface. Indicated for persons who have never fully recovered from the effects of some previous illness. General venous stasis, bluish skin, limbs cold.

Ans: Literally means hydrates of carbon. Carbohydrates are polyhydroxy (more than one OH group) aldehyde or polyhydroxy ketoneas in monosachharides; their olymers as in oligo and polysaccharides; their reduction products as polyhydric alcohols; oxidation products as aldonic, uronic, sacharic acid; substitution products as amino sugars.

2.    What is sugar?

Ans: The term sugar is generally restricted to those carbohydrates containing less than 10 monosaccharide residues.

3.    What is dextrin?

Ans: It is the intermediate products of the hydrolysis of starch and glycogen.

4.    What is exergonic reaction?

Ans: That portion of energy change during a reaction which is available to do work is termed the free energy change, designated, “G. when “Gis negative the reaction is said to be exergonic.

5.    What is substrate level phosphorylation?

Ans: Whenproductionof ATPfromADPtakesplacedirectlyduring a reaction, the process is known as substrate level phosphorylation.

6.    Why carbohydrate is a metabolically essential?

Consumption of fruit and vegetables has dramatically increased globally during the past a few decades. These are living perishable biological entities which perform a number of metabolic functions and have a short life span. Once the fruit is harvested, respiration and transpiration continue, but only for as long as the fruit can draw on its own food reserves and moisture. It is this limited ability to continue vital metabolic functions which define fruit as perishable. It is also estimated that about 20% of all fruits and vegetables produced are lost each year due to spoilage. The process of the fruit spoilage is just the decomposition of the fruit itself. Once harvested, this begins to deteriorate until eventually it becomes unfit for consumption. This deterioration is known as decay and that leads to spoilage. Latter may be defined as “any sensory change (physical, visual, olfactory or flavour) which the consumer considers to be unacceptable. The gradual changes which cause deterioration and decay in fruits are due to certain organisms and chemicals present in the food and outside the food. Carbohydrates play a major role in the fruit spoilage process (Prasanna et al., 2007) by way of depolymerization leading to decreased molecular size with concomitant increase in the levels of ripening inducing specific enzymes, whose target differ from fruit to fruit. The major classes of cell wall polysaccharides that undergo modifications during ripening are pectins, cellulose, starch, and hemicelluloses (Hallet et al., 2005). The focus of this chapter is to provide information about carbohydrate metabolism during fruit spoilage.

Carbohydrate metabolism in the cell is essentially the metabolism of glucose and other substances related to glucose in their metabolic processes. The chemical reactions involved in carbohydrate metabolism represents complex groups, sequences, and cycles of reactions which integrate at various points with the reactions concerned in the metabolism of lipids and proteins. The major types of chemical processes involved in carbohydrate metabolism may be grouped as follows: a) Anabolism of starch – Photosynthesis, b) Catabolism of starch, c) Catabolism of glucose – 1. Glycolysis and TCA cycle and 2. Oxidative pentose   phosphate pathway.
 
Plant cells “burn “ glucose for energy. Plants also produce sugars through photosynthesis. This is roughly the reverse of the burning process.

Introduction

Carbohydrates are the most common source of energy for all living cells, which, in presence of light, are formed by the green plants from CO₂ and water during photosynthesis. It canbe said that ‘light’ is theultimatesourceof energyrequired for all livingcells.Glucose,a monosaccharide,plays a centralroleincarbohydrate metabolismin all plants, animals and manymicroorganisms. Glucose is derived from the polysaccharides (starch, glycogen) and non-carbohydrate sources (amino acids, glycerols, etc.) during metabolism and ultimately converted either into carbondioxide and water orotherintermediateproducts.Complete oxidation of glucose to CO₂ and water provides ~2,840 kJ/mol energy. The other monosaccharides such as fructose, galactose, mannose, etc. are also important molecules in carbohydrate metabolism.

The most abundantly and commonly available compounds in the plant kingdom are carbohydrates. They comprise saccharides viz.

Monosaccharides - glucose, fructose etc.

Disaccharides - sucrose, lactose, maltose etc.; and

Polysaccharides - starch, cellulose etc.

Cellulose is the major component of plant cell wall.

The active groups in carbohydrates are aldehyde (-CHO) and ketone (=CO). In addition, they contain hydroxyl groups as well. The chemical properties of saccharides vary depending upon the number of hydroxyl groups and the presence or absence of (–CHO) or (=CO) groups.

1. Carbohydrates are primarily composed of the elements
   1. Carbon, hydrogen and oxygen
   2. Hydrogen, oxygen and carbon
   3. Oxygen, carbon and hydrogen
   4. None of these
2. Carbohydrates have an empirical formula
   1. (CH₂O)_n
   2. (CH₂O)_n+₁
   3. (CH₂O)_n-₁
   4. (CH₂O)_n/₂

Carbohydrates are the most abundant biomolecules on earth. They occur in nature as glucose, starch and cellulose etc. Each year, photosynthesis converts more than 100 billion metric tonnes of carbon dioxide and water into starch, cellulose and other plant products. Carbohydrates are polyhydroxy aldehydes or ketones and their derivatives. They provide 4K calories of energy per gram. They promote utilization of lipids and reduce wastage of proteins. They are readily available in roots, tubers, cereal grains, sugarcane and sugar beet.

Carbohydrates have the general formula C_n( H₂O)n, indicting that they are the hydrates of carbon. Some carbohydrates also contain nitrogen, phosphorous or sulfur. They are characterized by the number of carbon atoms they contain. If n=3, they are trioses, n=4 tetroses, n=5 pentoses, n=6 hexoses and n=7 heptoses. The most common sugars in plants are the hexoses. Two or more simple carbohydrates condense together to form polymer sugars like sucrose, starch and cellulose etc. The basic condensing bond is glycosidic bond.

Carbohydrates are the macronutrients consisting of carbon (C), hydrogen (H), and oxygen (O) atoms. In simpler terms, carbohydrates can be defined as polyhydroxy aldehydes or ketones or substances, which yield them on hydrolysis. The general formula of carbohydrates is Cn (H2 O)n , where n is the number of carbon atoms. In nature, carbohydrates are the most abundant biological molecules. In the human diet, carbohydrates are one of the main nutrients that provide energy to the body. The green plants, through the process of photosynthesis, synthesize the carbohydrates.

Classification of carbohydrates

Carbohydrates are also known as saccharides, originating from the Greek word sakcharon, which means sugar. However, not all saccharides have a sweet taste. Carbohydrates can be classified into three distinct groups: monosaccharides, oligosaccharides, and polysaccharides. The number of sugar units determines this classification.

Monosaccharides

Monosaccharides, or simple sugars, are the most basic carbohydrates. They are the monomers that serve as the building blocks for forming polymers or complex carbohydrates. Monosaccharides are the most simple carbohydrates possessing carbonyl groups, i.e., aldehyde (CHO) and ketone (C=O) groups with two or more hydroxyl (OH) groups. Monosaccharide has the generic formula Cn (H2 O)n, where n is the number of carbon atoms. Monosaccharides are sugars that cannot be hydrolyzed further to form simple carbohydrates. These crystalline solids without color dissolve in water but remain insoluble in non-polar solvents.

Carbohydrates are synthesized from CO₂ and H₂O in chlorophyll containing plants during photosynthesis. The term carbohydrate was originally coined for this class of compounds as most of them were hydrates of carbon or could be represented by the general formula C_n(H₂O)n. Not all the carbohydrates however, have this empirical formula, for example deoxyribose (C₅H₁₀O₄) and glucosamine (C₆H₁₃O₅N). Further lactic acid (C₃H₆O₃) formaldehyde (HCHO or CH₂O) and acetic acid (CH₃­.COOH or C₂H₄O₂) with this general formula is not a carbohydrate. Carbohydrates are defined as the compounds having either an aldehyde or a ketone group or a modified aldehyde or ketone group and other carbon atoms with alcoholic (-OH) group. Hence the continued usage of the term carbohydrate is for convenience rather than exactness.
