Ferns lack alternation of generation while mosses show the same.
Mosses are facultative aerobes while ferns are obligate aerobes.
Vascular bundles of ferns show xylem vessels while those of mosses lack it.
Sporophytes of ferns live much longer as compared to the sporophytes of mosses.

Pyrenoids contain protein besides starch.
Sexual reproduction may be isogamous, oogamous and anisogamous in green and brown algae.
Some of the members of algae also occur in association with fungi (lichen) and animals (eg, on sloth bear).
The leaves in pteridophytes are well adapted to withstand extremes of temperature, humidity and wind.
In angiosperms, each embryo sac has a three-celled egg apparatus one egg cell and two synergids, three antipodal cells and two polar nuclei.
All seed bearing plants i.e., gymnosperms and angiosperms follow dipontic life patterns of plants.
In gymosperms, roots in some genera have fungal association in the form of mycorrhiza (Pinus) while in some others (Cycas) small specialized roots called coralloid are associated with N2 fixing cyanobacteria.
