During embryo sac formation in plants, the megaspore mother cell undergoes meiosis to produce four haploid cells. One of these cells develops into the embryo sac, which contains the egg cell, central cell, and other supporting cells. The embryo sac is a crucial step in the development of the female gametophyte in plants.
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.
The formation of seeds is a result of the fertilization of eggs within the embryo sac. After pollination occurs and sperm cells from the pollen reach the egg cell in the embryo sac, fertilization takes place resulting in the development of a seed.
An amniotic sac is a fluid-filled sac that surrounds and protects the embryo during development in utero. It helps provide a cushion against physical impact and keeps a stable environment for the embryo to grow.
The polar nuclei in an embryo sac are involved in the process of double fertilization in plants. One of the polar nuclei fuses with a sperm cell, leading to the formation of endosperm tissue, while the other polar nucleus may fuse with another sperm cell or remain unfertilized. The endosperm provides nutrients for the developing embryo in seeds.
The amniotic membrane forms a protective sac that surrounds the embryo during development. It is filled with amniotic fluid that cushions and protects the developing embryo/fetus.

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.

The protective structure that forms around an embryo is called an amniotic sac or amnion. This sac contains the amniotic fluid that cushions and protects the developing embryo during pregnancy.
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.
The protective structure that forms around a human embryo is called the amniotic sac or amnion. This sac contains amniotic fluid, which cushions and protects the developing embryo during pregnancy.
The amniotic sac is the structure that protects and cushions the embryo during pregnancy. It is filled with amniotic fluid that helps absorb shocks and regulate temperature for the developing fetus.
