Vedclass · Answer

(D) In $Mangifera$ (Angiosperms) and $Pinus$ (Gymnosperms),the male gametes are non-motile.$1$. $Mangifera$ is an angiosperm,and in angiosperms,pollen grains carry non-motile male gametes to the ovule through a pollen tube.$2$. $Pinus$ is a gymnosperm,and in gymnosperms,male gametes are also non-motile and are transported via pollen tubes.$3$. In contrast,algae like $Ulothrix$,$Chara$,and $Spirogyra$ typically produce motile male gametes (antherozoids) that require water for fertilization.
