Question

What is the best explanation for the process of transpiration in plants? A. It is the evaporation of water from leaf stomata, which helps in xylem transport. B. It is the condensation of water droplets on leaf surfaces, which helps in phloem transport. C. It is the property of water molecules to adhere to the xylem wall while traveling against gravity.

Answer 1

The best explanation for the process of transpiration in plants is option A. It is the evaporation of water from leaf stomata, which helps in xylem transport. This evaporation of water in the leaves is released to the atmosphere as a vapor. A process called guttation occurs during transpiration wherein the water loss is in a form of liquid from the stem or leaf of the plant.

Answer 2

Answer:

Option A, t is the evaporation of water from leaf stomata, which helps in xylem transport.

Explanation:

Transpiration is the process in which water is taken up by the plants from the roots and then it is transported to the leaves and then released to the atmosphere. The leaves have stomata at their bottom , which opens up and release the water in the form of vapour. In Xylem transport , water is transported from the roots to all part of the plant body, since water transportation is involved in transpiration process , it is said to be helping in xylem transport.

Thus, option A is the correct answer.
