Question

Loss of water from the tip of the leaf pores in a plant is known as
A. Transpiration.
B. Guttation.
C. Evaporation.
D. Respiration.

Answer 1

The substances that are emitted out through exudation are referred to as exudates. Plant cells regularly utilize nutrients like sugar, amino acids for the system of cellular respiration. Transpiration takes place through the minute pores on the floor of a leaf called, stomata. Plants lose gallons of water each day via the process of transpiration.

Complete explanation:
Option A: The loss of water from the plants is recognized as Transpiration. The procedure of evaporation of water to the atmosphere from the leaves of a plant in the form of water vapor is known as transpiration. Stomata are tiny pores present on the decrease side of the leaves that help in the exchange of gases and water vapor.
Hence, A is incorrect.
Option B: The soil is rich in moisture content where the water floods a plant root system. Leaves can keep only a finite amount of water. The excess water i.e., xylem sap is taken out from the roots through the edge of leaves and this technique is known as guttation. Therefore, the loss of water from the tips of leaves is known as guttation.
Hence, B is the correct answer.
Option C: In evaporation water changes from a liquid to a gas or vapor below the temperature at which it boils and it occurs on the surface of a liquid. It does not include the loss of water from the tip of the leaf pores in a plant.
Hence, C is incorrect.
Option D: Cellular respiration is the technique of evaporation of water from the aerial parts of a plant. These aerial components might also consist of leaves, roots, stems, and flowers. Only a small amount of water is used by way of the roots for the growth and metabolism of the plant.
Hence, D is incorrect.

Hence, Option B is the correct answer.

Note:
Bleeding or exudation is the process of emission of fluids from pores or wounds of the plant. of the water is lost by the plant via the procedure of guttation of transpiration. The most frequent oxidizing agent for cellular respiration is oxygen. Molecular oxygen offers most of the chemical energy required for cellular respiration.
