Botany
In seed plants (gymnosperms like Pinus, Cedrus, Ginkgo, Sequoia; angiosperms like Salvia and Wolffia), the gametophyte is highly reduced and is retained within the sporophyte. This retention ensures nourishment and protection of the gametophyte by the sporophyte. In pteridophytes like Salvinia and Selaginella, the female gametophytes in these plants are
retained on the parent sporophytes for variable periods.
Equisetum, Lycopodium and Adiantum are homosporous pteridophytes → their gametophyte is free-living, not retained.
Polytrichum and Funaria are mosses → gametophyte is independent, dominant generation.
