Back to the Let’s see howthey are classified!

Vascular Plants

Roots – the plant’s anchor

Root hairs take in H20 and nutrients.Some roots store extra food and water

Types of RootsProp – Above the ground

Fibrous – Look like tree branches – help prevent erosionTaproots – Single thick root that reaches deep into the ground

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 PhloemTubes 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.

Tree trunks are vascularThe center of the trunk is made of old clogged tubes

or hardened xylem called heartwood. Sapwood or phloem surrounds the heartwood and

carries water & nutrientsEach 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!
