Question

leaves of a healthy potted plant were coated with Vaseline will this plant remain healthy for long give reasons for your answer

Answer 1

The plant leaves coated with vaseline will not remain healthy due to the following reasons:-
1) The vaseline coating will block the stomata. 
2) The exchange of gases will not take place. 
3) Photosynthesis and transpiration will not take place.

Answer 2

No, the plant will not remain healthy because vaseline would form a layer on the leaves and would affect the plant in the following ways :

• It would block the stomata and as a result ,no gases exchange and transpiration would take place .
• There would be no upward movement of water and minerals as there would be no transpiration. It would further affect the process of photosynthesis .Hence, plant will not remain healthy and would die eventually.
