Notes
Development of seed:
- In angiosperms, the seed is the final product of sexual reproduction.
- It is often described as a fertilized ovule.
- Seeds are formed inside fruits.
- A seed typically consists of seed coat(s), cotyledon(s), and an embryo axis.
- The cotyledons of the embryo are simple structures, generally thick and swollen due to the storage of food reserves (as in legumes).
