ABy meiosis inside the ovary wall
BBy binary fission of the spores
CBy fragmentation of leaf tissue
DBy mitosis in multicellular parts
Answer & Solution
Correct answer: D. By mitosis in multicellular parts
1. Plants have two distinct stages in their life cycle, the gametophyte stage and the sporophyte stage.
2. The haploid gametophyte produces male and female gametes by mitosis in distinct multicellular structures.
3. Fusion of those gametes forms the diploid zygote, which develops into the sporophyte.
4. Meiosis belongs to the other half of the cycle, where the diploid sporophyte produces spores.
5. This regular switch between the two stages is the alternation of generations.
