In the alternations of generations life cycle, which cellular division process is used to create gametes?
A
Meiosis
B
Mitosis
Verified step by step guidance1
Understand the concept of alternation of generations, which is a life cycle that alternates between a multicellular haploid phase (gametophyte) and a multicellular diploid phase (sporophyte).
Recognize that in the alternation of generations, the gametophyte is the haploid phase that produces gametes.
Recall that gametes are haploid cells, meaning they contain a single set of chromosomes.
Identify that in the gametophyte phase, gametes are produced through mitosis, not meiosis, because the gametophyte is already haploid and mitosis maintains the chromosome number.
Differentiate this from the sporophyte phase, where meiosis occurs to produce haploid spores from a diploid organism, which then grow into the gametophyte.
