Question: When an organism has a life cycle with alternation of generations, the haploid generation is the _______?
Options:
Zygote
Gametophyte
Gamete
Sporophyte
Alternation of generations is a type of life cycle found in plants and some algae. It involves a distinct alternation between two different generations:
-Gametophyte (Haploid): This generation is haploid, meaning it has one set of chromosomes. It produces gametes (sperm and egg) through mitosis.
-Sporophyte (Diploid): This generation is diploid, meaning it has two sets of chromosomes. It produces spores through meiosis.
📌 Other Options Explanations:
-Zygote: A diploid cell formed by the fusion of two gametes. It marks the beginning of the sporophyte generation.
-Gamete: A haploid reproductive cell (sperm or egg).
-Sporophyte: The diploid, spore-producing generation in the alternation of generations life cycle.
