Explanation
Meiosis in Plant Life Cycle Produces Haploid Gametes
Steps:
- Identify meiosis as the reduction division that halves chromosome number for gamete formation.
- In plant life cycles, meiosis occurs in reproductive structures to produce spores.
- For male gametes, this happens in anthers, forming pollen grains.
- Review diagram stages to match pollen with meiosis location.
Why A is correct:
- Meiosis in plants produces haploid microspores that develop into pollen grains, per the alternation of generations in the plant life cycle.
Why the others are wrong:
- B. Seed: Forms after fertilization, involving diploid embryo development via mitosis.
- C. Mature plant: Diploid sporophyte stage, where growth occurs by mitosis, not meiosis.
- D. Daughter plant: Results from seed germination or asexual reproduction, without reduction division.
Final answer: A
