Vedclass · Answer

(C) In $Fucus$ (a brown alga),the life cycle is diplontic.In a diplontic life cycle,the diploid sporophyte is the dominant,photosynthetic,and independent phase.The gametes are produced by meiosis,and the zygote is the only diploid stage (sporophytic phase) that represents the transition before the next generation.Therefore,the sporophytic phase is not independent or photosynthetic in the form of a multicellular plant body; rather,the multicellular plant body itself is the sporophyte.Thus,Assertion $(A)$ is true,but Reason $(R)$ is false because the sporophyte in $Fucus$ is the main plant body,not just the zygote,and it is independent and photosynthetic.

Assertion $(A)$: In $Fucus$,the sporophytic phase is limited to the zygote only.
Reason $(R)$: In $Fucus$,the sporophytic phase is photosynthetic and independent.
