Which of the following phrases characterizes alternation of generation in algae?

sporophytic generation getting converted into gametophytic generation in unfavorable conditions

diploid gametophytic generation alternating with haploid sporophytic generation

diploid sporophytic generation alternating with haploid gametophytic generation

Answer

The correct answer would be "Diploid sporophytic generation alternating with haploid gametophytic generation"

Alternation of generation refers to the type of life cycle often observed in lower plants. In this life cycle, plants alternate between diploid and haploid stage.

For example, a diploid sporophyte produces haploid spores through meiosis

The spores mature into haploid gametophyte which produces haploid gametes through mitosis.

The gametes fertilize and restore the ploidy by producing a diploid zygote which matures into a diploid sporophyte.
