BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Glucose is usually converted into starch for storage. Starch is better for storage than glucose because it is insoluble. Plants like potatoes and other tubers, and also fruits like the banana store starch for later use. This starch is stored by special organelles, or cell subunits called amyloplasts.

Detailed explanation-2: -During the night, when photosynthesis is not possible, plants must rely on stored reserves of carbohydrates built up during the previous day. In many plants, this carbohydrate is stored in chloroplastic starch granules which are degraded during the night to produce sugars.

Detailed explanation-3: -Answer and Explanation: In potato cells, starch is converted from glucose by specialized cell organelles called amyloplasts. Amyloplasts are a kind of leucoplast or unpigmented plastid. Amyloplasts also transfer the polymerized starch into another organelle called the stroma for storage.

Detailed explanation-4: -In order to prepare for times that less glucose is available or, like the case of potatoes, to prepare for future growth, plants need to store this glucose.

Detailed explanation-5: -Starch is stored in chloroplasts in the form of granules and in such storage organs as the roots of the cassava plant; the tuber of the potato; the stem pith of sago; and the seeds of corn, wheat, and rice.
