Question

Starch grain in potato tuber is located in

• A. Mitochondria
• B. Chloroplast
• C. Leucoplast
• D. Ribosomes

Answer 1

The correct option is C Leucoplast

There are three types of plastids chloroplast, chromoplast, and leucoplasts. Chloroplasts contain chlorophyll and carotenoid pigments which are responsible for trapping light energy essential for photosynthesis. In the chromoplasts, fat-soluble carotenoid pigments like carotene, xanthophylls and others are present. This gives the part of the plant a yellow, orange or red colour. The leucoplasts are the colourless plastids of varied shapes and sizes with stored nutrients. Amyloplasts is a type of leucoplast which stores carbohydrates (starch), e.g., potato, elaioplasts store oils and fats whereas the aleuroplasts of leucoplast store proteins.

So, the correct answer is option C.
