The embryo sac of a flower contains the female gametophyte, which typically consists of seven cells: one egg cell, two synergids, three antipodal cells, and one central cell containing two polar nuclei. The egg cell is involved in fertilization, while the synergids assist in guiding the pollen tube. The central cell, when fertilized, develops into the endosperm, which nourishes the developing embryo. Overall, the embryo sac plays a crucial role in sexual reproduction in flowering plants.
What else can I help you with?
What is the function of the embryo sac in a flower?
its the ovary
What is a ovule part of the female flower?
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.
What is function of ovule?
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.
What is embryo's organ of respiration nourishment and excretion?
Amniotic sac
What is the fluid-filled sac surrounding the developing embryo or fetus?
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.
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.
What is the function of the embryo sac in a flower?

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 a ovule part of the female flower?
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.
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 an embryo sac?
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.
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 fate of embryo in the embryo sac?
no
