Antipodal cells in plants provide support for the embryo sac and have a role in the development of the endosperm. They are also involved in the release of nutrients to support embryo development.
The ovule is the part of the flower where the embryo sac is housed, and the embryo sac contains the female gamete (egg), which, when fertilized by the sperm in a pollen grain, will produce a zygote. What was once a flower will become a fruit. The zygote develops in the ovule, and forms the seed, which will eventually be dispersed from the fruit to start a new generation. So, the ovule is analogous to the pollen: one contains the female gamete, and the other contains the male gamete.
The main function of the ovule is to house and protect the female reproductive cells (eggs) of the plant. Once fertilized by pollen, the ovule develops into a seed, which contains the embryo of the plant.
Amniotic sac
The fluid-filled sac surrounding the developing embryo or fetus is called the amniotic sac. It is filled with amniotic fluid that protects and cushions the fetus, helping to regulate its temperature and provide room for movement.
The embryo sac is the female gametophyte in a flower. It is located within the ovule and contains the egg cell, synergids, and antipodal cells. The embryo sac plays a crucial role in the process of fertilization in plants.
endosperm and dicot
Well, the plant is not mature enough for fertilization until a single large nucleus within the embryo sac divides to form an egg and two synergids. When the pollen tubes in the flower allow sperm cells to enter the embryo sac, the sperm cell unites with the egg. A double fertilization process happens when other sperm cells penetrate deeper into the nucleus.
The protective sac around the embryo or fetus is the amniotic sac.

The number of cells within an embryo sac is typically equal to the number of nuclei within the embryo sac. This is because each cell of the embryo sac contains one nucleus, and during the process of embryo sac development, the number of cells and nuclei increase concurrently.
A fluid-filled sac that surrounds an embryo is called an amniotic sac. This sac contains amniotic fluid, which provides protection and cushioning for the developing embryo.
An embryo sac is a structure found within the ovule of a flower where female gametophyte development takes place. It is a small sac-like structure that contains the egg cell along with other cells involved in the process of fertilization and seed formation.
The protective sac surrounding the embryo is formed by the amniotic membrane and the amniotic fluid which together create the amniotic sac. This sac serves to cushion and protect the developing embryo during pregnancy.
Antipodal cells in plants provide support for the embryo sac and have a role in the development of the endosperm. They are also involved in the release of nutrients to support embryo development.
