Plant Divisions

Bryphytes: branch of plant science that involves mosses, liverworts, and hornworts.  It is most common in wet areas where they provide a habitat for tiny animals.  They do not contain vascular tissue and therefore are "nonvascular" plants

Pteridophytes: seedless vascular plants that include lycophytes, ferns, whisk ferns,and horsetails.  they have roots that is similar to the early vascular plants.  Early vascular plants formed during the Carboniferius period.

Coniferophyla: It is the largest of the four gymnosperm phylum.  It includes pines, firs, spruces, larches, yews and junipers. There are about 550 species left and only a few dominate the Northern Hemisphere. They are mostly evergreen.  These plants are able to survive stressful environments

Angiosperms: These are flowering, vascular seed plants that produce fruits and flowers.  It is very diverse and it widely distributive around the world.  There is currently 250,000 known species.  There are two classes that make up the angiosperm: monocots and dicots.  Monocots  have leaves with veins running parallel while dicots ahve netlike venation on their leaves.
