Question

why does waterlogged kill plants roots

Answer 1

Answer:

plants die under water logged condition because soil gets fully saturated with water which leads to deficient oxygen supply to the roots and prevents carbon dioxide to diffuse away. Oxygen deficiency in roots causes a switch from aerobic to anaerobic respiration.

Answer 2

Answer:

The principal cause of damage to plants grown in waterlogged soil is inadequate supply of oxygen to the submerged tissues as a result of slow diffusion of gases in water and rapid consumption of O2 by soil microorganisms. Oxygen deficiency in waterlogged soil occurs within a few hours under some conditions.
