Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are amyloplasts?
A
Non-pigmented storage organelles within plant cells
B
A molecule which turns into a helix as a result of glycosidic bonds
C
Pigmented storage organelles within plant cells
D
An unbranched polymer
Explanation: 

Detailed explanation-1: -Amyloplasts are specifically a type of leucoplast, a subcategory for colorless, non-pigment-containing plastids. Amyloplasts are found in roots and storage tissues, and they store and synthesize starch for the plant through the polymerization of glucose.

Detailed explanation-2: -Amyloplasts are plant-specific organelles responsible for starch biosynthesis and storage. Inside amyloplasts, starch forms insoluble particles, referred to as starch grains (SGs).

Detailed explanation-3: -An amyloplast is a leucoplast. It doesn’t have pigment or color. Leucoplasts are found in a variety of non-photosynthetic plant tissues and serve various functions, including, as in the case of an amyloplast, the storage of starch.

Detailed explanation-4: -Leucoplasts. These are the non-pigmented organelles which are colourless. Leucoplasts are usually found in most of the non-photosynthetic parts of the plant like roots. They act as a storage sheds for starches, lipids, and proteins depending on the need of the plants.

Detailed explanation-5: -Amyloplasts are found in many tissues, particularly in storage tissues. They are found in both photosynthetic and parasitic plants, i.e. even in plants that are not capable of photosynthesis. Many amyloplast proteins are also expressed in photosynthetic tissue.
