The embryo sac is contained within the ovule of seed plants. It is a female gametophyte that typically contains seven cells, including one egg cell, two synergids, three antipodal cells, and one central cell with two polar nuclei. This structure plays a crucial role in fertilization and the development of seeds. After fertilization, the embryo sac develops into the seed, containing the embryo and stored nutrients.
What else can I help you with?
What is the sac which contains fluid to protect the embryo called?
The Amniotic Sac
What is a fluid-filled sac that surrounds an embryo?
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.
What is the relationship between the number of cells within an embryo sac and the number of nuclei within the embryo 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.
Is the embryo sac male or female?
The embryo sac is female, as it is the structure within the ovule of a flowering plant that contains the female reproductive cells (eggs).
What is the embryo sac in a flower?
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.
During embryo sac formation what happens?
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.
What is the name for the protective structure that forms around an embryo?
Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
What is the name for the protective structure that forms around a human 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.
What is the protective sac around the developing embryo or fetus is the?
The protective sac around the embryo or fetus is the amniotic sac.
What is the fate of embryo in the embryo sac?
no
What is the name of the fluid-filled bag of thin tissue that developes around the embryo soon after implantation?
amniotic sac
The protective sac surrounding the embryo is formed by the?
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.
