Answer:
Gametes through mitosis
Explanation:
Most organisms including plants undergo a life cycle where they alternate between a diploid phase (sporophytic) and haploid phase (gametophytic). The sporophyte in organisms like plant is the actual plant itself that results from the fusion of male and female gametes.
These gametes that fuses are produced from the gametophyte of an organism. The male gametophyte produces the male gamete called SPERM while the female gametophyte produces the female gamete called EGG. The gametophyte is a haploid (n) body that results when specialized cells of the diploid (2n) sporophyte undergoes meiosis, reducing its chromosmal number by half.
Hence, the haploid gametophyte only needs to undergo mitotic division, which is a division that produces identical copies of daughter cells, to form gametes with the same haploid (n) chromosomal number.
The male and female gametophyte generate gametes by the process of mitosis.
Se-xual reproduction in plants:
In distinct groups of plants, se-xual reproduction occurs with little variations. The plants possess two different stages in their life cycle, the gametophyte stage and the sporophyte stage.
The haploid gametophyte produces the female and male gametes by the process of mitosis in different multicellular compositions. The combination of the female and male gametes produces the diploid zygote that develops into the sporophyte.
Post attaining maturity, the diploid sporophyte generates spores by the process of meiosis, which further differentiates by the process of mitosis to generate the haploid gametophyte.
Thus, both male and female gametophytes produce gametes by the process of mitosis.
