Structure and development of Seed | Seed Formation | Reproduction
Here's an overview of the structure and development of a seed:
Seed Structure:
1.Seed Coat(Testa): Outer protective layer.
2.Embryo.Immature plant, consisting of:
Radicle(Root): Develops into primary root.
Hypocotyl(Stem): Develops into seedling stem.
Cotyledons(Leaves): First leaves, often stored food.
3.Endosperm: Nutritive tissue, providing food for embryo.
4.Micropyle: Opening in seed coat for water uptake.
Seed Development:
1.Ovule (Female Reproductive Cell): Develops into seed.
2.Fertilization: Pollen fertilizes ovule, forming zygote.
3.Embryo Formation: Zygote develops into embryo.
4.Endosperm Formation: Triploid tissue develops from fusion of pollen and ovule nuclei.
5.Seed Maturation: Embryo and endosperm grow, seed coat forms.
6.Seed Dormancy: Seed enters resting state, awaiting favorable conditions.
7.Germination: Seed absorbs water, embryo grows, and seedling emerges.
