Question

Are there three types of plastids namely: chloroplasts, chromoplasts and lecolasts? (there are given two types of plastids in the chapter )

Answer 1

Yes, there are 3 different types of plastids:

• Chloroplasts: They have chlorophyll as a pigment. Their function is to carry out photosynthesis. They are green in color because of presence of chlorophyll.
• Chromoplasts: They have different kinds of carotenoid pigments which are responsible for color so they can be of any color like red, yellow or orange depending upon the type of pigment they have. They are usually present in the petals of flower in order to make flower attractive to pollinators.
• Leucoplasts: They store lipids, proteins and starch. They are colorless in appearance.
