Text Solution

Verified by Experts

The correct Answer is:
D
Oxygen is required by the germinating seed during aerobic respiration, it is the main source of energy for the seedlings until the formation of leaves. Oxygen is an atmospheric gas that is found in soil pore spaces. If a seed is buried too deeply within the soil or the soil is water logged, the seed can be oxygen starved. If germinating seeds do not get air for respiration, they are still capable of respiration in absence of oxygen. Anaerobic respiration takes place in the seeds in the absence of free oxygen.
