which of the following types of algae shows a distinct alternation of generations?
This way, there is alternation of two haploid generations (gametophyte) with one diploid (sporophyte) generation. Such life-cycle is known as haplobiontic type of life-cycle. There is distinct alternation of generations in the higher red algae, e.g., Polysiphonia. The plants are different in their chromosome numbers as well as in functions. The sexual plants bear male and female sex organs on them, and the asexual plants bear tetraspores.
