How are plants classified?
How plants transport
water:
1. vascular plantssystem of tubes that connect leaves, stems & roots - moves water & nutrients
adds support - plants can get big
1. vascular plantsexamples:
grass dandelions celery
vascular plantssystem 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 plantsmake seeds & flowers
2. conifersmake seeds but do not make flowersgrow 2 kinds of cones
3. sporesferns & mossesdo not make seeds
