Bryophytes.
-Includes: mosses, liverworts and hornworts
-Called “non-vascular plants” because their dominant stage (gametophyte) lacks vascular tissues
- Show many of the characteristics believed to be in the first land plants

Pteridophytes.
-They utilize the Alternation of Generations life cycle
- The do not produce seeds (thus they are called the “seedless vascular plants”)
- The sperm must swim from the antheridium to the archegonium
- They also lack vascular tissue in their hyphae (root-like)

Bryophyte vs Pteridophytes
Bryophytes
-Non-vascular -Needs to be around water -Its dominant stage is gametophyte |
Pteridophytes
-Vascular -Doesn't always need to be around water, just in damp areas -Its dominant stage is sporophyte |
Bryophyte: Mosses and liverworts.
