The alternation of generations involves alternating between a haploid (n) stage and a diploid (2n) stage. This pattern is seen in many plants, algae, and some fungi, where the haploid stage produces gametes (sex cells) that fuse to form a diploid zygote, which then develops into the diploid stage. The diploid stage then produces spores that undergo meiosis to form the haploid stage once again. In this way, the organism spends roughly equal amounts of time in both the haploid and diploid stages. Choices A, B, D, and E do not accurately describe the alternation of generations.
