Which of the following pair of plastids - thing stored is NOT correct?

I. Amyloplasts - oils and fats

II. Aleuroplasts - carbohydrates

The correct answer is Both I and II.

• Both pair is not correct.

Key Points

• Amyloplasts:
  • ​Amyloplasts are plastids that make and store starch in internal membrane spaces.
  • Amyloplasts store carbohydrates (starch), e.g., potatoes. Hence pair I is not correct.
  • Inside amyloplasts, starch forms insoluble particles referred to as starch grains.
  • They are frequently discovered in the tissues of vegetative plants, such as tubers (potatoes) and bulbs.
  • Amyloplasts are also hypothesized to play a role in plant root growth in a downward direction and gravity sensing (gravitropism).
• Aleuroplasts:
  • A leucoplast kind of plastid called an aleuroplast is used to store proteins. Hence pair II is not correct.
  • They are commonly found in seeds.

Additional Information

• Elaioplasts:
  • The fats and oils that the plant needs are stored by elaioplasts.
  • Monocotyledon plant seeds and liverworts both contain it.
• Chromoplast:
  • Chromoplasts are carotenoid-accumulating plastids.
  • They give various tubers and roots, along with a variety of flowers and fruits, their color.
