Ferns, Whisk ferns, and Horse Tails
Name 6 unique characteristics of Pterophyta
- 1.Has true roots, leaves, and stems.
- 3.Fronds(babies are fiddleheads)

Term for all petals
Starting at the release of spores, moss life cycle
- 1.Spore release
- 2.Grows to male and female gametophytes
- 3.Male releases sperm from antheridium
- 4.Sperm reaches female archegonium
- 5.Egg is fertilized and remains in archegonium.
- 6.Sporophyte parasitizes the gametophyte; meiosis occurs here in the sporophyte.
- Back to 1
Starting at the release of spores, fern life cycle
- 1.Spores release
- 2.Spores develope into bisexual gametophyte
