Q

What are most vascular seedless plants

A

homosporous

25
Q

What do the homosporous spores give rise to

A

bisexual/monoecious gametophyte

26
Q

How do homosporous bryophytes differ from homosporous vascular seedless

A

Bryophytes tend to have spores give rise to male and female gametophytes on different plants whereas vascular seedless tends to give rise to monoecious plants
