The immediate product of meiosis in flowering plants is the…
A. sporophyte
B. gametophyte
C. zygote
D. pollen grains
QUICK ANSWER…
B
DETAILS…
During alternation of generation in flowering plants, the diploid sporophytes undergo meiosis to produce spores which over time develop into haploid gametophytes; these gametophytes use mitosis to produce egg and sperm which fuse together to form a diploid zygote cell (and ultimately leads to a return back to the sporophyte stage).
Now to the right option…
- Option A is incorrect; the sporophyte stage is formed after the two products of mitosis, egg and sperm, fuse together to form a diploid cell.
- Option B is partially correct; the gametophyte is not the immediate product of meiosis in flowering plants, the immediate product is simply called spores, it is these that develop into gametophyte. If spores had been part of the option, it would have been the perfect answer. In the absence of spores as an option, haploid gametophyte becomes the closest valid option.
- A zygote is a diploid cell formed when the male sperm mixes with the female egg for fertilization, this occurs after mitosis. So, C is incorrect.
- Actually, D is also incorrect; pollen grains are more advanced in stage.
QUICK ADVICE…
You may please note that:
- These questions are set and answered by imperfect beings, sometimes slight error could actually be coming from the typists; your responsibility should be to be sure of what you are doing.
- In the absence of what looks like the perfect answer, please choose the nearest option available, if you are sure all options are wrong, you may ignore and move on to the next question.
