Detailed explanation-1: -Amyloplasts are leucoplasts that function mainly in starch storage. They are colorless and found in plant tissues that do not undergo photosynthesis (roots and seeds). Amyloplasts synthesize transitory starch which is stored temporarily in chloroplasts and used for energy.

Detailed explanation-2: -Amyloplasts and chloroplasts are closely related, and amyloplasts can turn into chloroplasts; this is for instance observed when potato tubers are exposed to light and turn green.

Detailed explanation-3: -Amyloplasts are plastids or organelles responsible for the storage of starch granules. The rate of starch synthesis in cereal grains is one of the factors affecting both grain size and yield (Kumar and Singh, 1980).

Detailed explanation-4: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
