spores

154
Q

usually photosynthetic, the gametophytes are one cell layer thick, less than half a

Q

most fern species have one type of ____, which is both fertile and
photosynthetic

frond

163
Q

some species have separate sterile and fertile fronds, with the sterile/fertile fronds
being mainly non-photosynthetic

A

sterile

164
Q

o the sporangia on fertile fronds typically occur in groups called

Q

▪ arrangements vary greatly among species, but ____typically appear as
random dot-like structures on the frond surface or at the edge of fronds

A

sori

bracken ferns

A

rhizomes

173

they do so through special filaments that detach from ____and
develop into new plants
