What is the Difference Between Embryo Sac and Endosperm?
🆚 Go to Comparative Table 🆚The main difference between an embryo sac and endosperm lies in their functions and location within the plant.
Embryo Sac:
- Develops within the ovule of flowering plants.
- Contains the egg cells and other structures involved in sexual reproduction.
- Produces an egg cell for the purpose of fertilization.
- Develops before fertilization.
Endosperm:
- Develops within the seeds of flowering plants.
- Provides nutrition in the form of starch, proteins, and lipids to the developing embryo.
- Formed from the primary endosperm nucleus.
- Develops after fertilization.
In summary, the embryo sac is a structure present in the ovule of flowering plants that contains the egg cells and is involved in sexual reproduction. In contrast, the endosperm is a structure present in the seeds of flowering plants that provides nutrition to the developing embryo and develops after fertilization.
Comparative Table: Embryo Sac vs Endosperm
Embryo sac and endosperm are two distinct structures found in the seeds of angiosperms, and they play crucial roles in the plant's reproductive process. Here is a table highlighting the differences between them:
Feature | Embryo Sac | Endosperm |
---|---|---|
Function | Produces an egg cell for fertilization | Provides nutrition to the developing embryo |
Location | Ovule within the flower | Seed of the flower |
Development | Forms before fertilization | Develops after fertilization |
Structure | Female gametophyte | Triple-layered structure surrounding the embryo |
Fertilization | Union of the egg cell with a sperm | Fusion of a sperm with the primary endosperm nucleus |
In summary, the embryo sac is a female gametophyte structure that develops within the ovule and produces an egg cell for the purpose of fertilization. In contrast, the endosperm is a nutritive structure that forms after fertilization and provides nutrition to the developing embryo in the form of starch.
