Question

The process of losing water by plants is called---
A. Evaporation
B. Transpiration
C. Condensation.
D. Translocation.

Answer 1

Hint: Transpiration is the biochemical mechanism by which plants remove excess water from their aerial components. Water passage through a plant and evaporation from aerial sections such as branches, roots, and flowers is known as transpiration. Plants use water, but only a small portion of the water soaked up by their roots is used for growth and metabolism. Transpiration and guttation lose the remaining \[97-99.5\% \].

Complete answer:
Option A: Evaporation is a form of vaporization that occurs on a liquid's surface as it transitions from a liquid to a gas. The evaporating liquid must not be saturated in the surrounding steam. As the molecules of a solvent collide, they transfer energy to one another depending on how they collide.
So, option A is incorrect.
Option B: Plants lose water by a mechanism known as transpiration. It's the mechanism by which plants absorb water from their roots and then release it through pores in their leaves as water vapor.
So, option B is correct.
Option C: The change of water from a gaseous state (water vapor) to a liquid state is known as condensation (water). Hot air rises, cools, and loses the ability to retain water vapor, resulting in condensation in the atmosphere.
So, option C is incorrect.
Option D: In the green areas of plants, which are usually branches, photosynthesis produces glucose. After that, it's turned into sucrose. The transfer of sucrose and other chemicals such as amino acids around a plant are known as translocation.
So, option D is incorrect.

Hence, Option B is the correct answer.

Note:
Plants, like all living things, need an excretory mechanism to remove excess water from their bodies. The term "transpiration" refers to the method of removing extra water from the plant's body. The most prevalent reason is water evaporation from the surface of the leaves. Water molecules in the plant tissues are separated from the aerial portions of the plants during transpiration. Plants only use a small portion of the water they consume for growth and production. The remainder is expelled by transpiration.
