Embryo Sac in Angiosperms
Angiosperms, also known as flowering plants, are the most diverse group of land plants. They are characterized by the presence of flowers and the production of seeds enclosed within a fruit. The embryo sac is a specialized structure found within the ovule of angiosperms.
Haploid or Diploid Cells?
The embryo sac is a haploid structure, which means that its cells contain only one set of chromosomes. The cells of the embryo sac are formed by the process of meiosis, which reduces the number of chromosomes in the cell by half. This is important because the embryo sac will ultimately give rise to the female gametophyte, which is the haploid structure that will fuse with the male gamete to form a diploid zygote.
The cells of the embryo sac are also unique in that they are not all the same. There are a total of eight nuclei within the embryo sac, which are divided into three types of cells: the egg cell, the two synergids, and the three antipodal cells.
Function of Embryo Sac
The embryo sac plays a crucial role in the reproductive process of angiosperms. It is the site of fertilization, where the male gamete fuses with the female gametophyte to form a zygote. This zygote will eventually develop into an embryo, which will be enclosed within a seed.
In addition to its role in fertilization, the embryo sac also plays a role in the development of the endosperm. The endosperm is a nutritive tissue that surrounds the embryo within the seed. It is formed by the fusion of the second male gamete with two polar nuclei within the embryo sac.
Conclusion
In conclusion, the cells of the embryo sac in angiosperms are haploid. They are specialized structures that play a crucial role in the reproductive process of flowering plants. The embryo sac is the site of fertilization and the development of the endosperm, which are both essential for the production of seeds.
