Answer 2

Answer:

Type # 1.Haplontic

There is a single vegetative individual or somatic phase. It is haploid and is often called gametophyte. The haploid plant body may be unicellu­lar, colonial or multicellular. It can multiply vegetatively and by accessory spores or mitospores.

Type # 2. Diplontic

There is a single somatic phase or vegetative individual. It is diploid and is often called sporophyte though it produces gametes in its body or sex organs. The diploid plant body is elaborated by the growth of the diploid zygote.

Type # 3. Haplodiplontic

This type of life history involves the sequential recur­rence of two well developed somatic phases or vegetative individuals, gametophyte and sporophyte. The sporophyte possesses diploid chromo­some number (2n). Meiosis takes place in it at the time of formation of meiospores.
