Question

Why do seeds germinate better in the dark?

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. Most of the seeds germinate best in dark environments
5. The presence of light tends to inhibit their growth.
6. The light decomposes carbonic acid gas and expels oxygen which leads the seed to harden.
7. These gases are key factors that promote germination.
8. In dark environments, the gases remain undisturbed and germination is favoured.
