Question

What is the function of plastids?

• A. Leucoplasts store the reserve food in the form of starch grains or oil droplets or proteins.
• B. Chromoplasts help in pollination and dispersal of seeds and fruits.
• C. Chloroplasts are sites of photosynthesis so are called kitchens of cell.
• D. All of the above.

Answer 1

The correct option is D All of the above.

Plastids are the cytoplasmic organelles found only in plant cells. On the basis of pigments present, plastids are of three types:

(i) Leucoplasts (colourless plastids)

(ii) Chloroplasts (green coloured plastids)

(iii) Chromoplasts (coloured plastids other than green).

Leucoplasts are for storage of starch grain and oil drops. Such colourless plastids are present in underground roots, stems.
Chloroplasts are mainly for photosynthesis. They are present in leaves.
Chromoplasts are responsible for the characteristic colour of flower and fruit. They are involved in attracting insects, various vectors for pollination and for fruit dispersal.
