Ch. 1 Lesson 3
How are plants
classified?
biologists
sort plants
by how they:
1.
transport
water
2.
reproduce
How plants
transport water:
1. vascular plants
system
of tubes
that connect
leaves, stems &
roots - moves
water &
nutrients
adds support plants can get
big
1. vascular plants
examples:



grass
dandelions
celery
vascular plants
system of tubes that connect leaves, stems & roots - moves water & nutrients
2. nonvascular plants
do NOT have:
 system of tubes
 true roots
 stems
 leaves
Examples of
nonvascular
plants:
1. mosses
largest
group of
nonvascular plants
Reproduce by spores
2. hornworts
3. liverworts
How plants
reproduce:
1. flowering plants
make
seeds & flowers
 make
2. conifers
seeds but do not make flowers
 grow 2 kinds of cones
3. spores
ferns
& mosses
do not make seeds
