Vedclass · Answer

(A) In most algae,the zygote undergoes meiosis to form haploid spores,resulting in a haplontic life cycle (e.g.,Chlamydomonas). However,some algae exhibit different patterns. Ectocarpus,Polysiphonia,and Kelps (large brown algae) exhibit a haplo-diplontic life cycle,where both haploid and diploid phases are multicellular. Chlamydomonas is the exception here as it exhibits a strictly haplontic life cycle,whereas the others listed are examples of haplo-diplontic life cycles.
