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 leaves of a healthy plant coated with vaseline will not remain healthy because the vaseline coating will block the stomata. As a result, The plant would not get oxygen for respiration. It would not get carbon dioxide to carry out photosynthesis.

Answer 2

Answer:

If leaves of a healthy potted plant are coated with Vaseline, it will clog the stomatal pores on leaves. Blockage of stomata will stop transpiration and exchange of gases from leaves. Transpiration plays an important role in ascent of sap in plants. Hence, lack of transpiration will stop ascent of sap. Moreover, stoppage of exchange of gases would also stop respiration and photosynthesis in leaves. This will result in death of leaves and finally the plant would die due to lack of food.
