Question

What happens if stem of a plant is completely covered with wax? Guess and write?​

Answer 1

Stem covered with wax

Explanation:

We are addressing a hypothetical situation or an experiment here where the stem of a plant is covered with wax. Assuming this plant has leaves and the leaves are not covered with wax, the plant can still respire. The wax coating will help the plant retain water. This plant will not wilt easily.

Desert plants are covered by wax to minimize loss of water. But they do not have leaves. They stem respires through stoma.

Answer 2

If stem of a plant is completely covered with wax, the loss of water is prevented.

• Transpiration takes place from the aerial parts of plants such as leaves, stems, etc.

• Plants have stomata that help in the exchange of gases such carbon dioxide and oxygen.

• However, in addition to that, transpiration takes place and water is lost from the plants through these openings.

• Therefore, to prevent further loss of water from the stems, it is covered with wax.

• It is mainly seen in case of desert plants where there is water scarcity.
