This is because animals and human have Enzyme amylase that can convert starch in simple sugar that can be used by it's cell to release energy. plant doesn't have the enzyme that convert glycogen into a form that can be utilized by it's body cells
In a plant, carbohydrates are stored in the form of starch.
in the form of the polysaccharide starch
Carbohydrates are absorbed and converted into glucose. The glucose can be stored as glycogen in the liver and the muscle tissue. If these are full the glucose will be converted into fat and stored.
Animals convert glucose to glycogen for longer term storage. In humans, glycogen is stored in the liver. Glycogen will be used before fat reserves are tapped.
Glycogen is a multibranched polysaccharide that serves as a form of energy storage in animals and fungi. In humans, glycogen is made and stored primarily in the cells of the liver and the muscles, and functions as the secondary long-term energy storage (with the primary energy stores being fats held in adipose tissue).
Amylopectin is a branched chain polymer of glucose found in plants, while glycogen is a highly branched polymer of glucose found in animals and humans. Both serve as storage forms of glucose, with glycogen being the main form of energy storage in animals and humans, while amylopectin is the main form of energy storage in plants.
cellulose
internal energy reserve io humans in the form of carbohydrates is 'glycogen'.
Living organisms have two major ways to store energy. They use molecules such as, glycogen and triglycerides, to store energy in the form of covalent chemical bonds. Lipids also store energy in living organisms.
STARCH in plants. GLYCOGEN in animals.
glycogen work as researve food material ih animal while aminoglycans are the modified carbohydrates and play imp. role in humans in the formation of cartilage, tenden etc.
humans store the energy from starch as glycogenBoth starch and glycogen are are polymers formed from sugar molecules called glucose and they serve as energy storage.
Glycogen is the form in which animals and humans store glucose. Plants on the other hand store their glucose as starch.
