I am in a ninth grade class and am doing a report on the classification 
of plants.  The sub-categories we are studying are: Vascular Plants; 
there roots, stems, and leaves;  Simple Vascular Plants, complex Vascualr 
plants; Gymnosperms,Angiosperms;  Nonvascular Plants; mosses, 
liverworts,hornworts, and algae.  I would appreciate any information that 
you can give me for any of those subjects.
