Function of the root hair cell

Absorbs water from the roots

Adaptations of the root hair cell

• extended cell membrane - large surface area to absorb water

• no chlorophyll - no need underground

• many mitochondria - active transport to absorb minerals

Function of the Xylem

Transports water throughout the plant

Adaptations of the Xylem

• not living -

• strengthened with lignin - support plant

• no cell wall/membrane at end - connects to other plants

Function of the Phloem

Transports Sugars throughout the plant

Adaptations of the Phloem cells

• Form sieve tubes(joined at end) - fast transport of sugars

• many mitochondria - release energy for active transport
