HORTICULTURE

Detailed explanation-1: -Diploid sporophyte cells undergo meiosis to produce haploid spores. Each spore goes through mitotic divisions to yield a multicellular, haploid gametophyte . Mitotic divisions within the gametophyte are required to produce the gametes. The diploid sporophyte results from the fusion of two gametes.

Detailed explanation-2: -Diploid Sporophyte Cells A sporophyte is a structure that has been formed from a diploid structure called a zygote. This zygote is resulted due to the fusion of two haploid gametes: male and female gametes. The formed zygote is later developed into a sporophyte, a diploid multicellular structure.

Detailed explanation-3: -The sporophyte is diploid, but the spores are haploid. The spores disperse and germinate into new gametophytes, repeating the process (see Figure 1.4. 1).

Detailed explanation-4: -In plants, alternation of generations exists, where the members have haploid and diploid phases. The plant’s haploid phase is called gametophyte and the diploid phase is called the sporophyte.

Detailed explanation-5: -The sexual phase, called the gametophyte generation, produces gametes, or sex cells, and the asexual phase, or sporophyte generation, produces spores asexually. In terms of chromosomes, the gametophyte is haploid (has a single set of chromosomes), and the sporophyte is diploid (has a double set).
