Why do plants in waterlogged soil often wilt despite plenty of water?
ALight intensity drops, halting transpiration
BSoil temperature rises and burns the root surface
CPhloem tissues stop working in the wet conditions
DRoots run short of oxygen and stop absorbing water
Answer & Solution
Correct answer: D. Roots run short of oxygen and stop absorbing water
1. Roots need oxygen for respiration to absorb water actively.
2. Waterlogged soil drives air out of pore spaces.
3. Without oxygen, roots cannot absorb water and the plant wilts.
4. So option A is correct.
