Question

If potted plant is covered with a glass jar water vapour appear in the glass jar why?

Answer 1

Answer:

Epidermis of a leaf is not continuous at all the places due to the presence of small pores, called stomata. ... During transpiration water vapour escapes through stomata opening, this results in appearance of water vapour on the wall of glass jar, if a potted plant is covered with it.

Answer 2

Due to transpiration, the plotted plant is covered with a glass jar, water vapor appears

Why water vapor appears on it?

• The stomata which are present in the plant helps in the exchange of gases in it.
• If the leaves are covered with a glass jar then stomata do not exchange gases
• Due to which gases around the leaves do not evaporate and water vapor appears

What is Stomata?

• It is pore present on the surface of the leaves
• It helps in the respiration process of plants
• It evaporates water vapor on the leaves
