• 500,000 amd 1000

• 750,000 and 3500

Plants share a common ancestor from the algae in the form of

• chlorophytes

• charophytes

Plants had to adapt to land by

• avoiding dessication (drying out)

• develop structural support

• develop an area where there is rapid cell division called the apical meristem

• development of xylem and phloem

True or False Plants developed an ability to be poisonous, produce noxious smells, and taste bad to avoid predators.

• True

• False

Bryophytes include

• mosses

• hornworts

• liverworts

• ferns

Bryophytes are

• relatives of early terrestrial plants

• include mosses, hornworts, liverworts

• live in damp habitats

• contain no xylem or phloem

What are tracheophytes?

• vascular plants that contain xylem and phloem

• plants with a trachea to bring in oxygen

• plants that live in or near water

• plants that live on land

Xylem transports

• food

• water

• oxygen

• nutrients

Phloem transports

• sugars

• proteins and other solutes throughout the plant

• water

• oxygen

Roots

• contain vascular tissue

• transfer water and minerals from the soil to the plant

• anchor the plant

• provide no structural value to the plant
