Male and female gametophytes do not have free independent existence in...
Explanation:
Cedrus
Cedrus is a gymnosperm, specifically a coniferous tree. In gymnosperms like Cedrus, the male and female gametophytes do not have free independent existence.
Male and Female Gametophytes
In gymnosperms, the male gametophyte is the pollen grain, which is produced within the male cone. The female gametophyte is the ovule, which is produced within the female cone. These gametophytes are not free-living structures like in other plants such as mosses or ferns.
Funaria, Polytrichum, and Pteris
In contrast to Cedrus, plants like Funaria (a moss), Polytrichum (a moss), and Pteris (a fern) have independent male and female gametophytes that can exist and develop separately from the sporophyte generation.
Life Cycle
In plants like Funaria, Polytrichum, and Pteris, the gametophytes are the dominant generation in the life cycle, while the sporophyte generation is more reduced. This is different from gymnosperms like Cedrus, where the sporophyte generation is dominant and the gametophytes are not free-living.
Conclusion
In summary, while male and female gametophytes have free independent existence in plants like Funaria, Polytrichum, and Pteris, they do not have this independence in gymnosperms like Cedrus.
