\rightarrow Spirogyra is an alga. It shows the haplontic life cycle.

\rightarrow Fern is a pteridophyte. The dominant phase of the life cycle is diploid sporophyte. Its gametophyte  is called prothallus

\rightarrow funaria is a bryophyte. Its gametophyte is a leafy stage

\rightarrow Cycas is a gymnosperm. The main plant body is sporophyte (2n). They have highly reduced gametophyte stage.
