Question

In "higher" plants the sporophyte phase is formed after growth and development of the zygote,point out the type of cell division involved in this growth

Answer 1

The zygote formed by fusion of male and female gametes is diploid .In higher plants this diploid zygote shows mitotic division to form the diploid plant body which is called sporophyte.sporophyte is the diploid multicellular stage in the life cycle of a plant or alga. It develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent.

Answer 2

In the sporophyte phase of the higher plants, the development and growth of the zygote occurred.

This development is mainly due to the fusion of female and male gametes in a diploid manner.

Also, the diploid zygote that is formed in the higher plants displays the body of the plant clearly.
