Which of the following is an example of alternation of generations? which of the following is an example of alternation of generations? a diploid cell divides by mitosis to produce two diploid daughter cells, which then fuse to produce a tetraploid cell. a haploid mushroom produces gametes by mitosis, and the gametes undergo fertilization, which is immediately followed by meiosis. a diploid animal produces gametes by meiosis, and the gametes undergo fertilization to produce a diploid zygote. a diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte).

A diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte).

Explanation:

Alternation of generation is a process that occurs in plants and refers to change from sexual haploid to asexual diploid stages and vice versa.

Gametophyte  is haploid stage ( n chromosomes), alternates with a sporophyte, which is diploid ( 2n chromosomes). A mature sporophyte produces spores by meiosis, (reduction cell division) which reduces the number of chromosomes to half, from 2n to n (diploid to haploid).
