Question

All plastids have similar structure because they can

• A. Store starch, lipids and proteins
• B. Get transformed from one type to another
• C. Perform same function
• D. Be present together

Answer 1

Answer: (B)

Get transformed from one type to another

• Plastid is an important site for the manufacture and storage of chemical compounds used by the cells of autotrophic organisms.
  
• They are of different types- chloroplasts (green plastids for photosynthesis), chromoplasts (coloured plastids for pigment synthesis) leucoplasts (colourless plastids for monoterpene synthesis).
• All plastids have similar structure because plastids can get transformed from one type to another.
  
• For example-

1. Conversion of green tomatoes into red occurs mainly due to the formation of chromoplasts from chloroplasts.
2. The chlorophyll-containing chloroplasts mature into chromoplasts (red pigment) in tomato.

• So, the correct answer is 'Get transformed from one type to another'.
