[Campbell Biology P.652] Which of the following statements accurately describes a stage or p... | Practice Question

Which of the following statements accurately describes a stage or process in the life cycle of Laminaria as depicted in Figure 28.14?

  • A1: The sporophyte (2n) produces gametes directly by meiosis.
  • B1: Gametophytes (n) produce gametes by mitosis.
  • C1: Fertilization results in a haploid zygote.
  • D1: Zoospores are diploid and develop into sporophytes.

Explanation

In the Laminaria life cycle Figure 28.14 , gametophytes are haploid n . They produce haploid gametes sperm and eggs through mitosis. Meiosis occurs in the sporophyte to produce haploid zoospores, and fertilization results in a diploid zygote that develops into a new sporophyte.
