Questions 1 till 3

Plant cells: Root hair cells

Plant cells: Root hair cells

The long part increases the surface area (oppervlak) so the cell can absorb more water and minerals.

No chloroplasts! (Because it's under ground)

Plant cells: xylem and phloem

Plant cells: xylem and phloem

Xylem cells form hollow tubes and transport water from roots to leaves.

Phloem cells connect to each other and transport nutrients (food) down from the leaves.
