Question

Amyloplasts, elaioplasts and aleuroplasts belong to _______ category of plastids.

• A. Chloroplasts
• B. Chromoplasts
• C. Leucoplasts
• D. All of the above
  

Answer 1

The correct option is C Leucoplasts

Leucoplasts are colourless plastids which generally occur near the nucleus in the non-green cells and possess internal lamellae. There are three types of special leucoplasts: (i) amyloplasts which are starch containing leucoplasts, e.g., potato tuber. (ii) elaioplasts or lipidoplasts or oleoplasts which are colourless plastids and store lipids e.g., tube rose. (iii) aleuroplasts or proteoplasts or proteinplasts which are protein storing plastids, e.g., aleurone cells of maize grain, endosperm cells of castor.
