Plant Classification

Plants with Tubes

(Vascular Plants)

Kingdom: Plants

• all plants have many cells/cells have nuclei

• do not need to eat other living things to survive– make their own food

• Vascular plants: have tubes– tubes found in roots, stems, and leaves– water and nutrients enter plant through

roots• tubes carry water and nutrients through plant to

leaves

– food is made in leaves • different set of tubes carries food to parts of

plant

– Ferns are a type of vascular plant

• Trees are a type of vascular plant– trunk: largest woody steam– center of trunk: heartwood - made of hard,

dead calls– around heartwood: rings of sapwood

• living tubes that carry water and food are found in sapwood

– outside layer: bark - dead cells that protect the living sapwood

• any plant that has flowers or cones is a vascular plant

Plants without TubesNonvascular plants

• nonvascular plants: do not have tubes– moss is a nonvascular plant

• water must soak into plants– passes from cell to cell– food travels with water

• because of this nonvascular plants must live in damp places (lots of water to soak)

• do not grow tall or large

• need fertile, moist soil

• have no roots, stems, or leaves

Summary

• Plants classified in 2 groups– Vascular plants: have tubes

• Carry water and nutrients in tubes• Grow tall

– Nonvascular plants: no tubes• Take in water from environment• Need to live in moist place• Do not grow tall or large
