Solution
The correct options are
A to enable the process of photosynthesis.
B to enable the transport of water and mineral from soil to leaves.
C it enables the plant to maintain concentration of the sap.
Transpiration is the loss of water in the form of water vapour from the aerial parts of a plant. The heat required for this evaporation is obtained from the plant itself (latent heat) and thus the plant cools itself when it is hot outside.
Transpiration helps the plant in the following other ways too:
1.Roots continuously absorb water from the soil. If excess water is not evaporated out, the sap would become dilute, preventing further absorption of water and minerals.
2.Water absorbed is used for photosynthesis.
3.The water in the plant body, both in xylem and phloem, transports substances in solution from one part to the another.
