Question

Which of the following types of plastid does not contain stored food material?

• A. Chromoplasts
• B. Elaioplasts
• C. Aleuroplasts
• D. Amyloplas

Answer 1

Answer: (A)

Chromoplasts

Answer 2

Chromoplasts are yellow or reddish in colour because of the presence of carotenoid pigments. They do not contain stored food material. Chromoplasts are formed either from leucoplasts or chloroplasts. Chromoplasts provide colour to many flowers for attracting pollinating insects. They provide bright red or orange colour to fruits for attracting animals for dispersal. Amyloplasts are starch containing leucoplasts, e.g., potato tuber. Elaioplasts or lipidoplasts or oleoplasts are colourless plastids which store lipids e.g., tube rose. Aleuroplasts or proteoplasts or proteinoplasts are protein storing plastids, e.g., aleurone cells of maize grain, endosperm cells of castor.
