In which one of the following, the male and female gametophytes don't have free-living independent existence?
Pteris
Funaria
Polytrichum
Cedrus
Solution
Cedrus is a gymnosperm having reduced dependent gametophytes- pollen and endosperm. In gymnosperms the male and the female gametophytes do not have an independent free-living existence and remain within the sporangia and are retained on the sporophytes. Hence, option D is correct.
