Root pressure is maximum when

Options

  1. ATranspiration is high and absorption is very low
  2. BTranspiration is very low and absorption is high
  3. CTranspiration and absorption both are high
  4. DTranspiration and absorption both are low.

Correct answer

B. Transpiration is very low and absorption is high

Step-by-step solution

Root pressure is the pressure that develops in tracheary elements of xylem due to the accumulation of water. It occurs due to active absorption of water and is maximum when the rate of absorption is high and the rate of transpiration is low.
