Question

Write down the names of post fertilization events in flowering plants. Describe the process of embryo development in dicot.

Answer 1

There are many events which take place after the process of fertilization. There is a formation of the zygote due to the fusion of the male gamete with the egg cell. The name of the events are endosperm and embryo development, maturation of the ovules to form seeds and maturation of the ovary to form fruit. The zygote divides to form two cells called as the terminal cell and basal cell. The basal cell divides to form the linear group of cells which is called as suspensor. The terminal cell divides to form the embryo. The embryo cells divide and forms different stages in the development phase. The first stage is the globular stage, followed by heart stage and then finally the torpedo stage. These names are given on the basis of the shape of the embryo. This embryo develops and matures inside the seed.
