Question

Do all plant cells have plastids?

Answer 1

Plastids:

1. Plastids are double-membrane organelles found in cells of both algae and plants.
2. Yes, all plant cells have plastids.
3. They help in the storage and synthesis of food by the plant.
4. There are various types of plastids:

• Chloroplast- These are sites for the synthesis of food by the photosynthesis process.
• Chromoplast- Chromoplast has carotenoid pigment that gives color to plant parts and it helps in attracting pollinators.
• Leucoplast- They are found in non-photosynthetic plant parts like roots and act as storage units for starch, lipids, and proteins.
