TRANSPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
This transpiration important in plants?
A
Water for photosynthesis
B
Transport amino acids and sucrose
C
Tranport mineral ions
D
To maintain the temperature of the plant
Explanation: 

Detailed explanation-1: -Transpiration results in transpiration pull which thereby increases the rate of absorption of water along with minerals from the soil through roots. Transpiration helps in transportation of absorbed minerals to all the parts of the plant.

Detailed explanation-2: -Minerals are transported by specific proteins present in the membrane of the root hairs. Transport proteins are embedded in the plasma membranes of endodermal cells and control the type and amount of solutes reaching the xylem.

Detailed explanation-3: -At the same time, plant transpiration provides evaporative cooling, forming a major component of the leaf energy balance. Transpiration also provides the driving force for transport of water and nutrients from roots to shoots.

Detailed explanation-4: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.
