Question

Which of the following is a type of plastid?

• A. Leucoplast
• B. Chromoplast
• C. Both A and B
• D. Chloroplast

Answer 1

The correct option is C Both A and B

In plants, plastids may be of different forms, depending on the function they play in the cell. Undifferentiated plastids (proplastids) may develop into any of the following variants:

• Chromoplasts - These are coloured plastids for pigment synthesis and storage. They usually have green pigment but may also contain yellow or orange pigments. Chloroplast is a chlorophyll (green pigment) containing chromoplast.
• Leucoplasts - These are white or colourless plastids for monoterpene synthesis; leucoplasts sometimes differentiate into more specialized plastids. These are primary organelles for the storage of starch, oils, and protein granules.

So, the correct answer is 'C'.
