Question

Name the storage form of carbohydrate in plants and animals.

Answer 1

Hint : A carbohydrate is a biomolecule made up of carbon (C), hydrogen (H), and oxygen (O) atoms, generally in a 2:1 hydrogen–oxygen atom ratio (as in water), and hence having the empirical formula $C_m(H_2O)_n$ (where m may or may not be different from n). However, not all carbohydrates (e.g., uronic acids, deoxy-sugars like fucose) meet this exact stoichiometric criterion, and not all compounds that do meet this criterion are automatically categorised as carbs (e.g. formaldehyde and acetic acid).

Complete Step By Step Answer:
Starch is a kind of carbohydrate that accumulates in plants as a polysaccharide. Polysaccharide is the storage form of carbohydrates in animals that are known as glycogen.
Starch, also known as amylum, is a polymeric carbohydrate made up of several glucose units linked together by glycosidic linkages. Most green plants generate this polysaccharide to store energy. It is the most prevalent carbohydrate in human diets, with substantial quantities found in basic foods such as potatoes, maize (corn), rice, wheat, and cassava (manioc). Pure starch is a white powder that has no flavour or odour and is insoluble in cold water or alcohol. The linear and helical amylose, as well as the branching amylopectin, make up this molecule. By weight, starch includes 20 to 25 percent amylose and 75 to 80 percent amylopectin, depending on the plant.
Glycogen is a multi branched glucose polymer that is used to store energy in mammals, fungi, and bacteria. The polysaccharide structure is the body's primary glucose storage structure. Glycogen is one of two types of energy reserves, with glycogen serving as a short-term reserve and triglyceride stores in adipose tissue (i.e., body fat) serving as a long-term reserve. Glycogen is produced and stored predominantly in the liver and skeletal muscle cells in humans. Glycogen can make approximately 5–6% of the fresh weight of the liver, and the liver of an adult weighing 1.5 kg may store about 100–120 gram of glycogen.

Note :
Polysaccharides are the most common sugars. A polysaccharide molecule might be found in thousands of units of glucose. These incredibly complex carbohydrates are made up of starches, cellulose, and glycogen. Starch and glycogen are two common methods for plants and animals to store carbohydrates as energy.
