Question

Why do some seeds fail to germinate?

Answer 1

Seed germination:

1. Seeds are ripened ovules that are formed when the embryo sac is fertilized by pollen.
2. Germination is the process by which a seed sprouts to give rise to new plants.
3. Factors that influence the seed germination process are water availability, aeration, temperature, light intensity, and viability.
4. A seed might fail to germinate due to multiple reasons.
5. Water is a key factor in promoting seed germination. Very less or too much water content can affect germination.
6. Lack of oxygen also inhibits seed germination and oxygen availability is directly linked to water availability.
7. Seeds germinate only when certain temperature ranges are present and fail if the temperature is too high.
