Seed
The matured and fertilized ovule, which comprises an active embryo reserve food and protective coating, is referred to as a seed. Seeds are ripened ovules that contain an embryonic plant with sufficient reserve food for embryo development. Ovules evolve into seeds after fertilization.
Types of Seed:
- Monocotyledonous seeds: Seeds having only one cotyledon, called monocotyledonous seeds.
- Dicotyledonous seeds: Seeds with two cotyledons, called dicotyledonous seeds.
- Albuminous seeds: Seeds having an endosperm. These seeds have thin membrane cotyledons and endosperm that hold on and feed the seedling during its early growth.
- Exalbuminous seeds: Food gathers in the endosperm tissue of exalbuminous seeds early in development, but it is utilized by the growing embryo and mature seeds without endosperm.
