6. What is the shoot system’s role?
To support the plant above ground and help in food preparation.
7. What are tendrils, and what is their function?

8. Which pigments help leaves perform photosynthesis?
Chlorophyll.
9. What are stomata, and what is their function?

By wind using their fluffy parachute-like structures.
14. What are examples of plants with underground modified stems?
Potato, garlic, onion, ginger.
15. What is vegetative propagation?
