Question

What are the stages of seed development?

Answer 1

Seed development:

1. Seed is the fertilised ovule formed after the successful sexual reproduction in angiosperms.
2. Seed contains an embryo enclosed within the seed coat.
3. Seed development starts with double fertilisation.
4. Double fertilisation results in the formation of a zygote.
5. Zygote forms the embryo and the primary endosperm nucleus (triploid).
6. The seed coat is derived from ovule tissues.

Three main stages of seed development are:

1. Cell division and differentiation.
2. Accumulation of food reserve.
3. Maturation and water loss.
