Question

Sporic meiosis occurs in

• A. Animals
• B. Thallophyta
• C. Bryophyta
• D. All plants except thallophyta

Answer 1

The correct option is D All plants except thallophyta

Sporic meiosis, has mitosis in two stages, both the diploid and haploid stages, termed diplobiontic.

Sporic meiosis occurs in all plants except thallophyta. In sporic meiosis, the division by mitosis happens to create a multicellular diploid organism, the sporophyte. Some of the cells of the sporophite then produce spores through a sporic meiosis. In this case, the meiosis is sporic (because it produces spores). The spores then produce a haploid gametophyte which, in turn, will produce the gametes through mitosis.
