Question

 Leaves of a healthy potted plant were coated with vaseline. Will this plant remain healthy for long? Give reason for your answer.

Answer 1

If leaves of a healthy potted plant were coated with vaseline, it will not remain healthy for long. Due to the coating of vaseline, the stomatal pores will be blocked. Hence, the plant will not be able to get oxygen for respiration and carbon dioxide for photosynthesis. Transpiration will also stop and the plant will ultimately die.
