What are the three subdivisions of the non vascular plants? - Answer liverworts, hornworts,
mosses
What are the advantages of plant evolution onto land? - Answer unfiltered sunlight, more
CO2, higher concentration of nutrients, few herbivores/pathogens, greater opportunity for
adaptive radiation
What are the main characteristics of nonvascular plants? - Answer no vascular tissue, no true
root, no true stem/leaves, semi-aquatic, require water for reproduction, cuticle, stomata,

diffusion

Vascular tissue that conducts most of the water and minerals upwards in the plant - Answer
xylem
,Vascular tissue that distributes sugars, amino acids and other organic products in varying
directions - Answer phloem
What is the purpose of leaves in vascular plants? - Answer Increases surface area for
capturing more sunlight
