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

The Figure shown below represents an activity to prove the requirements for photosynthesis. During this activity, two healthy potted plants were kept in the dark for 72 hours. After 72 hours, KOH is kept in the watch glass in setup X and not in setup Y. Both these setups are air tight and have been kept in light for 6 hours. Then, Iodine Test is performed with one leaf from each of the two plants X and Y.
