Root pressure is maximum when

Root pressure is maximum when

Options

  1. Atranspiration is high and absorption is low.
  2. Btranspiration is very low and absorption is high.
  3. Cboth are very high.
  4. Dboth are very low.

Correct answer

B. transpiration is very low and absorption is high.

Step-by-step solution

The positive pressure in the plants responsible for pushing up water in the stem is known as root pressure. The root pressure is observed maximum in the night or early morning when the evaporation is low and the water absorption is high due to excessive collection of water. Root pressure provides a push in the overall process of water transportation in plants.
