Detailed explanation-1: -In pteridophytes, the gametophyte is an individual that bears male and female reproductive organs and hence produces gametes. It may bear both male and female reproductive parts called monoecious or it may bear male and female reproductive parts on separate plants called dioecious.

Detailed explanation-2: -In homosporous pteridophytes, the gametophyte is bisexual and haploid. Pteridophytes have a sporophytic plant body and can produce either the same or two types of spores. If spores are produced on the same plant then the condition is called homosporous.

Detailed explanation-3: -In pteridophytes, gametophyte that develops in the homosporous species is usually. (1) Monoecious and has events, precursor to the seed habit.

Detailed explanation-4: -Bryophytes are homosporous and monoecious but marchantia is dioecious.
