Vedclass · Answer

(B) To determine which plants have dependent gametophytes,we analyze their life cycles:$1$. $(i)$ Marchantia (Liverwort) and $(ii)$ Sphagnum,$(iv)$ Polytrichum (Mosses): These are Bryophytes. Their gametophyte is the dominant,independent,free-living phase.$2$. $(iii)$ Pteris: This is a Pteridophyte. Its gametophyte (prothallus) is small,multicellular,and free-living.$3$. $(v)$ Pinus,$(vi)$ Cycas (Gymnosperms),and $(vii)$ Castor (Angiosperm): In these seed-bearing plants,the gametophytes are highly reduced and are completely dependent on the sporophyte for nutrition and protection. They do not have an independent free-living existence.Therefore,the plants where both male and female gametophytes are not independent are $(v)$ Pinus,$(vi)$ Cycas,and $(vii)$ Castor.The total count is $3$.
