Ch. 1 Lesson 3 How are plants classified?

biologists sort plants sort plants by how they: 1.transportwater2.reproduce

How plants transport water:

1. vascular plants ssystem of tubes that connect leaves, stems & roots - moves water & nutrients aadds support - plants can get big

e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

2. conifers mmake seeds but do not make flowers ggrow 2 kinds of cones

3. spores fferns & mosses ddo not make seeds

Biologists sort plants by how they: 1. t ransport water 2. reproduce

conifers  make seeds but do not make flowers  grow 2 kinds of cones

vascular plants  system of tubes that connect leaves, stems & roots -moves water & nutrients  adds support - plants can get big

nonvascular plants  Do NOT have: system of tubes true roots stems leaves

mosses  largest group of nonvascular plants

spores  How do nonvascular plants reproduce?

spores  ferns & mosses reproduce by

vascular or nonvascular ? celery vascular

vascular or nonvascular ? nonvascular hornworts

vascular or nonvascular ? dandelion vascular

vascular or nonvascular ? nonvascular liverworts
