Which of the following statements correctly describes a characteristic of the alternation of generations in plants, as illustrated in the provided diagram?

  • A: Both gametophytes and sporophytes are multicellular organisms.
  • B: Meiosis directly produces gametes in the sporophyte.
  • C: Fertilization results in the formation of a haploid zygote.
  • D: The sporophyte is typically haploid (n) while the gametophyte is diploid (2n).

Explanation

In the alternation of generations, both the haploid gametophyte and the diploid sporophyte stages are multicellular organisms. Meiosis produces spores, not gametes, and fertilization forms a diploid zygote. The sporophyte is diploid, and the gametophyte is haploid.
