Which among the following statement(s) is correct for haplodiplontic life cycle of plants?

Question

Verified by Toppr

Answer 1

Haplodiplontic life cycle is exhibited majorly by plants of Bryophyta and Pteridophyta but some algae like Ectocarpus, Polysiphoina and Kelp also show this type of life cycle. In haplodiplontic life cycle, the dominant phase may vary viz. a dominant haploid gametophyte will have short-lived multicellular sporophyte while a dominant diploid sporophyte will have short-lived gametophyte.
Hence, options 'A', 'C' and 'D' are correct.
