Question

Is the dependence of the sporophyte on the female gametophyte in ferns similar or different to the relationship between the sporophyte and the female gametophyte in bryophytes?

Answer 1

Ans - In bryophyta gametic phase dominates the life cycle and in ferns sporophyta dominates the life cycle.

In bryophyta sporophyte and gametophyte are physically connected. whereas in pteridophytes sporophyte and gametophyte are present on different plants and are not connected physically.

Sporophyte in bryophyta are dependent upon gametophyte for nutrition. on the other hand sporophytic plants in pteridophytes is independent and can perform photosyntheis.
