Let’s see how

they are classified!

slide9

Roots – the plant’s anchor

Root hairs take in H20 and nutrients.

Some roots store extra food and water

Types of Roots

Prop – Above the ground

Fibrous – Look like tree branches – help prevent erosion

Taproots – Single thick root that reaches deep into the ground

slide10

Stems

  • Hold plant up
  • Support leaves
  • Carry water and food to other
  • parts of the plant
  • Store water and food
  • Xylem
  • Tubes that transport water and nutrients
  • upward from roots to leaves
  • Phloem
  • Tubes that carry food to parts of the plant.

Woody Stems

like those found in trees…

Xylem

Tubes that transport water

and nutrients

upward from roots to leaves

Phloem

Tubes that carry food to

parts of the plant.

slide12

Tree trunks are vascular

The center of the trunk is made of old clogged tubes

or hardened xylem called heartwood.

Sapwood or phloem surrounds the heartwood and

carries water & nutrients

Each year a new set of tubes forms and an old set dies.

This adds a growth ring to the trunk.

That’s how we know how old a tree is!

Germinate sprouting of the seed

  • Conditions must be right!
  • Fertile soil
  • Warm temperatures
  • Enough moisture

Seed Germination
