Multiple Choice
In flowering plants, which of the following cell types is produced directly by meiosis?
A
Microspores and megaspores
B
Sperm cells and egg cells
C
Zygotes and endosperm nuclei
D
Pollen grains and embryo sacs (mature gametophytes)
Verified step by step guidance1
Understand the process of meiosis in flowering plants: Meiosis occurs in the reproductive organs to produce haploid cells from diploid cells.
Identify the diploid cells undergoing meiosis: In flowering plants, meiosis happens in the microsporangia (male) and megasporangia (female) to produce spores.
Recognize the products of meiosis: Meiosis produces haploid spores called microspores (male) and megaspores (female), which will develop into gametophytes.
Distinguish between spores and gametes: Microspores and megaspores are not gametes themselves but will develop into gametophytes that produce gametes (sperm and egg cells) by mitosis.
Conclude that the cell types produced directly by meiosis are microspores and megaspores, not sperm, egg cells, zygotes, endosperm nuclei, pollen grains, or embryo sacs.
