Question

why Seeds sown deep in the soil fail to germinate?​

Answer 1

Answer:

Oxygen is also essential for cellular respiration, so it must be present to allow the seed to begin to develop under the soil. That's why it's important not to plant seeds too deep. If they can't get enough oxygen underground, they will not be able to expand. So, the air is essential for the germination of the seed. Seeds planted deep in the soil do not germinate because they are unable to get enough oxygen.   Rapid cell division takes place during germination. Energy is needed for the division of cells. This energy is created by oxidation. The oxygen that is needed for oxidation is supplied by air.
