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
