Question

The process of transpiration in plants helps in the
A. Opening of stomata
B. Closing of stomata
C. Upward conduction of water and minerals
D. Both B and C

Answer 1

Hint: Transpiration is the process of removal of an excessive amount of water from the aerial plant parts. It keeps the cells turgid, cools the surface, and helps in transporting essential commodities such as water and minerals to the leaves.

Complete answer: Transpiration is a biological process of water removal in form of water vapors. This process takes place through the stomata.
The loss of water by the process of evaporation increases the water stress in the mesophyll cells due to the lower concentration of water.
Then, the water enters into mesophyll cells from the neighboring cells through the process of osmosis. Water evaporation results in the creation of suction pressure.
This force draws more water from the stem which causes roots to absorb more water from the soil.

Hence, the correct option is C Upward conduction of water and minerals.

Note: The intermolecular forces that exist between water molecules are known as cohesion and the force between the xylem vessel and the water molecule is termed as adhesion. Both these forces along with transpiration help in the upward conduction of water.
