DENDROLOGY

Detailed explanation-1: -Gametes develop in the multicellular haploid gametophyte (from the Greek phyton, “plant”). Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis.

Detailed explanation-2: -Sporophytes are plant generations that produce spores. Spores are produced by algae, bryophytes, angiosperms, and gymnosperms. A spore is a tiny structure that, after germination, gives rise to a new plant. Spores are classified into two types: mitotic spores and meiotic spores.

Detailed explanation-3: -During the sporophyte stage, the plant produces spores with diploid or two sets of chromosomes (2n) by the process of mitosis. These spores later develop into gametophytes that produce gametes having a haploid or single set of chromosomes (n) by the process of meiosis.
