Question: Describe the structure of a mature female gametophyte in angiosperms.
The mature female gametophyte in angiosperms is also known as the embryo sac. It is formed by the process of megasporogenesis and megagametogenesis, which occur within the ovule of the flower. The embryo sac typically consists of eight haploid nuclei, which are arranged in four groups: one egg cell and two synergids at the micropylar end, one central cell with two polar nuclei, and three antipodal cells at the chalazal end. The egg cell and the central cell are involved in fertilization, while the synergids and the antipodals have supporting roles.
