Question

What is germination what are its different types explain with examples

Answer 1

Germination is the beginning of growth of a seed. The seed must have the right level of warmth and moisture to begin to germinate. First, the seed leaves absorb moisture which allows the food reserves to become available to the new plant. It can then produce a root so that it can find its own water, followed by a shoot which develops from the plumule, which will allow it to absorb light. The plant needs both water and light to grow.

Sometimes, the seed leaves, or cotyledons, remain below the surface of the soil, as in germination of a Pea. This is called Hypogeal Germination.
In some species, the seed leaves remain on the new shoot and are brought above the ground, as in germination of the Ash tree. This is called Epigeal Germination.
