Seeds don't germinate when they go deep into the soil.give reason?

Answer:
Explanation:
Complete Answer:
- When a seed is planted in the soil, germination occurs. Germination is a phase in which the seed transitions from a dormant state to a developing, living plant. The seed contains a small plant embryo as well as all the nutrients that the developing plant requires to begin its growth cycle.
- Water is one of the most significant factors in the germination of seed. Water is necessary for cellular respiration which is a metabolic process.
- 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.
- When the seedling develops, it breaks out of the soil. After this stage, germination is complete, and the seedling can begin photosynthesis to gain energy. This will cause the developing seedling to straighten up into a tiny plant, heading for the sun.
Answer:
Rapid cell division occurs during germination. Cell division necessitates the use of energy. Oxidation is the source of this energy. The air provides the oxygen essential for oxidation. As a result, air is required for seed germination. Because they don't get enough oxygen, seeds planted deep in the soil don't germinate. As a result, the correct response is 'Unable to obtain sufficient oxygen.'
