Question

Why is moisture essential for seed germination?

Answer 1

Germination:

1. The beginning of growth of the seed into a new plant is called germination.
2. The embryo formed is later differentiated into plumule (shoot part), radicle (root part) and cotyledons.
3. Germination of a seed depends on a variety of factors such as water availability, oxygen, temperature etc.
4. Moisture aids by providing hydration for protoplasm's critical activities, dissolved oxygen for the developing embryo, softening seed coating, and increasing seed permeability.
