In the moss life cycle, where does meiosis occur?
A
In the sporangium of the sporophyte
B
In the archegonium of the gametophyte
C
In the rhizoid cells of the gametophyte
D
In the antheridium of the gametophyte
Verified step by step guidance1
Understand the moss life cycle: Mosses exhibit alternation of generations, which includes a haploid gametophyte stage and a diploid sporophyte stage.
Recall the role of meiosis: Meiosis is the process that reduces the chromosome number by half, producing haploid cells from diploid cells. This typically occurs in structures responsible for spore production.
Identify the sporophyte's function: The sporophyte is the diploid generation in mosses, and it produces spores through meiosis. Spores are haploid and will grow into gametophytes.
Locate the sporangium: The sporangium is a specialized structure within the sporophyte where meiosis occurs to produce haploid spores.
Eliminate incorrect options: The archegonium and antheridium are gametophyte structures involved in gamete production, not meiosis. Rhizoid cells are involved in anchoring the gametophyte and do not participate in meiosis.
