When a potted plant is flooded with water, the magnitude of root pressure _______.
Options:
A . Increases
B . Decreases
C . Remains unchanged
D . Becomes negative
Answer: Option B : B When the quantityof water in the soil is increased beyond a certain limit, it results in poor aeration of soil. This retards the metabolic activities of root cells, decreasingrespiration, hence, the rate of water absorption also decreases. And the magnitude of root pressure is dependent on the rate of water absorption.
