Chapter 28.1 Green algae and land plants

What is the common ancestor to all green plants

Green algae

What is the first evidence of land plants within nonvascular plants

Cuticle, pores, spores (in sporangium), complex gametophyte

What are some examples of nonvascular plants

Liverworts, mosses, hornworts

What do the first land plants not have?

Vascular tissue to conduct water and provide support

Are nonvascular plants sporophyte dominant or gametophyte dominant?

Gametophyte dominant

What are the major morphological innovations of seedless vascular plants?

Stomata, vascular tissue, roots, leaves

What do seedless vascular not have

They do not have seeds

Is seedless vascular plant sporophyte dominant or gametophyte dominant?

Sporophyte dominant

What is xylem tissue?

A part of vascular tissue that moves water and nutrients up then plant (only up)

What is phloem tissue

A part of vascular tissue that moves sugar around the plant (not only up)

What structure up makes up simple water conduction cell

Cellulose

What makes up the first vascular tissue

Cellulose and ligin

What are tracheids?

Type of water conducting cell found in all vascular plants

What do tracheids look like?

Thin vessels with angled ends attracted by ends

What do vessel elements look like?

Wide barrel shaped with wide ends, found in angiosperms

What are vessel elements?

Type of water conducting cell found in angiosperms

What are some examples of seedless vascular plants?
