Question

Plants require water for their survival. But when watered excessively, plants die. Discuss.

Answer 1

• Water is essential for the growth and survival of the plant.
• Excess water in the soil replaces the air spaces present in the soil and removes the trapped air in the soil.
• As a result, roots do not get oxygen for respiration, eventually root cells undergo cell death.
• This impairs the mineral and water transport that takes place through the roots.
• Hence, plants die.
