Which one of the following does NOT favour absorption of water in plants?

Options

  1. ALow concentration of solutes in soil water.
  2. BIncreased transpiration rates.
  3. CPresence of capillary water.
  4. DPoorly aerated soil.

Correct answer

D. Poorly aerated soil.

Step-by-step solution

Water absorption in plants depends on several environmental factors. Low concentration of solutes in soil water means the soil solution is hypotonic, which creates a favourable water potential gradient for water to enter the roots. Increased transpiration rates create a strong transpirational pull, which is the primary driving force for passive water absorption. Capillary water is the main source of available water for plants in the soil, so its presence favours absorption. Poorly aerated soil (such as waterlogged
