Vedclass · Answer

(C) The Assertion is correct because different plant groups (like algae,bryophytes,pteridophytes,gymnosperms,and angiosperms) exhibit distinct life cycle patterns such as haplontic,diplontic,or haplo-diplontic.However,the Reason is incorrect because the alternation of generation occurs between a haploid gametophyte $(n)$ and a diploid sporophyte $(2n)$,not the other way around. In plants,the gametophyte is haploid and the sporophyte is diploid.

$A$: Different plant groups show different patterns of life cycles.
$R$: During the life cycle,there is an alternation of generation between a diploid gametophyte and a haploid sporophyte.
