Gynoecium and its Components
The gynoecium is the female reproductive part of a flower, consisting of one or more pistils. Each pistil is made up of three main parts: stigma, style, and ovary. The ovary contains an ovarian cavity, which can have one or multiple chambers or locules. The placenta, where the ovules or megasporangia arise from, is located inside the ovarian cavity.
Binucleate Cell in the Embryo Sac
The embryo sac, also known as the female gametophyte, is a structure within the ovule where the female gametes are produced. It is formed through a process called megasporogenesis, which involves the development of megaspores within the ovule.
Among the cells present in the embryo sac, the central cell is binucleate. This means that it contains two nuclei within its cytoplasm. The central cell is located in the center of the embryo sac and is surrounded by other cells, such as the egg cell, synergids, and antipodal cells.
Functions of the Central Cell
The central cell plays a crucial role in the process of double fertilization, which is unique to flowering plants. During double fertilization, two sperm cells are involved: one fertilizes the egg cell to form the zygote, which develops into the embryo, and the other fertilizes the central cell to form the endosperm.
The endosperm is a nutrient-rich tissue that provides nourishment to the developing embryo. It is essential for the successful development and growth of the embryo. The central cell, being binucleate, undergoes fusion of one of its nuclei with a sperm cell, leading to the formation of the endosperm nucleus.
Conclusion
In summary, the binucleate cell in the embryo sac is the central cell. This cell plays a vital role in double fertilization, specifically in the formation of the endosperm, which is essential for embryo development and growth. Understanding the structure and function of the gynoecium and its components is crucial in studying the reproductive processes of flowering plants.
