Detailed explanation-1: -Potatoes synthesize and store these starches in organelles called amyloplasts (named for the starch amylose).

Detailed explanation-2: -Amyloplasts are plastids or organelles responsible for the storage of starch granules.

Detailed explanation-3: -The major proteins of potato tuber are stored in the vacuole and serve dual roles as storage proteins and stress-response proteins.

Detailed explanation-4: -While insoluble starch is stored in plastids, sucrose and fructans are generally soluble and accumulate in vacuoles. In most species, starch is predominantly utilized for diurnal carbon storage in leaves.

Detailed explanation-5: -Answer and Explanation: In plant cells the central vacuole holds water. When potato cells are placed in a hypertonic solution water in the vacuole will leave the potato cell. The cytoplasm is composed of water as well but it is the vacuole in plants that either gains or loses water.
