. Root pressure is maximum when


A: Transpiration is high and absorption low

B: Transpiration is very low and absorption is high

C: Transpiration is very high and absorption is high

D: Transpiration and absorption both are slow

 

Best Answer

Explanation

The pressure developed in the plant roots by absorption of nutrients from soil is referred to as root pressure.

Whereas, transpiration is the exhalation of water vapors via leaf stomata. Hence, when the water output i.e.,

transpiration is reduced and water input i.e., absorption is high, the root pressure is high as well.

Final Answer

Hence, option B. i.e., Transpiration is very low and absorption is high is the correct answer.
