In _______, female gametophytes stop their growth at 8 nucleate stages...
Angiosperms:
Angiosperms are flowering plants that produce seeds enclosed within a fruit. Female gametophytes in angiosperms go through a process called megagametogenesis, where they mature and develop to eventually form the embryo sac.
8-nucleate stage:
During megagametogenesis in angiosperms, female gametophytes reach the 8-nucleate stage. At this stage, the embryo sac consists of 8 nuclei, including three antipodal cells, two synergids, one egg cell, and two polar nuclei in the central cell. This stage is crucial for fertilization to occur successfully.
Stoppage of growth:
In angiosperms, including female gametophytes, growth and development are tightly regulated processes. Once the female gametophytes reach the 8-nucleate stage, their growth stops, and they are ready for fertilization to take place. This halt in growth ensures that the reproductive process is coordinated and successful.
Therefore, in angiosperms, female gametophytes stop their growth at the 8-nucleate stage as part of the reproductive cycle of flowering plants.
