Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Animals store carbohydrates as ____ while plants store carbohydrates as ____
A
glycogen, starch
B
sugar, starch
C
starch, glucose
D
glycogen, glucose
Explanation: 

Detailed explanation-1: -Plants store carbohydrates in long polysaccharides chains called starch, while animals store carbohydrates as the molecule glycogen. These large polysaccharides contain many chemical bonds and therefore store a lot of chemical energy.

Detailed explanation-2: -In animal cells, glucose is generally stored in the form of glycogen. This is done to not upset the osmotic balances in the cell. Glucose molecules are soluble in water and thus can cause the cell to become hypertonic. This will result in the entry of water molecules within the cells and cause it to lyse.

Detailed explanation-3: -Therefore, starch and glycogen are the storage form of carbohydrates in plants and animals.
