Answer 1

Answer:

1) Flat, Broad, Have chlorophyll,Have proper venation

2)Peristalsis

3)Waxy coating over leaves or closing up of stomatal pore by release of dormin ( a hormone)

4)It provides water to leaves. Its also provide water to cell to make it turgid

Answer 2

Answer 1 = The adaptations of leaf for photosynthesis are as follows

1. Large surface area for maximum light absorption.
2. Large surface area for maximum light absorption.Presence of chlorophyll containing chloroplasts.
3. Large surface area for maximum light absorption.Presence of chlorophyll containing chloroplasts.Presence of numerous stomach on the surface of leaf for gaseous exchange.

Answer 2 = The lining of the alimentary canal has muscles which contract rhythmically to push the food forward. This movement is known as peristalsis.

Answer 3 = Waxy leaf cuticle helps plants to prevent transpiration (loss of water through stomata).

Answer 4 = The transpiration stream helps the plant to maintain on adequate mineral uptake, as many essential minerals occur in low concentrations in the soil.
