Question 1

Root hair cell

Answer 1

Function: Absorb water
Long and thin cell
Large surface area to increase the rate of absorption
Large vacuole filled with sap to increase the movement of water up the xylem

Question 2

Xylem Cells

Answer 2

Function: Transport water from roots to stems
Strengthened cellulose wall
Contains lignin for extra strength
Hollow lumen to allow water to move through it

Question 3

Phloem cell

Answer 3

Function: Moves food substances that the plant has produces by photosynthesis
Cells are joined end-to-end and contain holes in the end cell walls, forming tubes to allows sugars to flow through easily

Question 4

Palisade cell

Answer 4

Function: Light absorption and photosynthesis
Large surface area
Packed with chloroplasts which absorb light energy for photosynthesis
