some of the starch free leaves were coated with wax on both the surface the plant was maintained under normal environmental condition at end of the experiment the wax coated leaves are likely to show
1.Accumulation of more water
2.Wilting of wax coated leaves
3.Increases across accumulation
4.Decrease in number of chloroplast
Dear student,
Ans.
Option 1) is correct: accumulation of more water.
Wax coating on both surface of leaves prevents the loss of water through transpiration. Hence, it leads to accumulation of more water on the leaf surface.
Loss of water through the pores present in leaves called stomata in the form of vapours is called transpiration. The stomata are the small pores present in the leaves. Transpiration helps the plants to take nutrients from soil. It also keeps the plant cool in hot weather conditions.
Regards

Role of transpiration in plants is as follows:
- Creates transportational pull for transport of water in plants.
- Provides water for photosynthesis.
- ​Helps in the uptake of minerals from soil to upper parts of plant.
- Cools the surface of the leaves (due to the evaporation of water).
- Keeps the cells turgid; hence, maintains their shape.
