Question:
Leaves of a healthy plant were coated with vaseline. Will this plant remain healthy for long ? Give reasons for your answer.
Solution:
The plant will not remain healthy for long. Vaseline covers the cuticle and blocks the stomata. As a result
- It is unable to obtain oxygen from air for respiration,
- It is unable to perform photosynthesis as no carbon dioxide diffuses from air.
- In the absence of transpiration, the leaves get heated up and injured.
