, They increase the surface area available for water to
move into the cell.
Give 3 adaptions of the They have a large permanent vacuole that speeds up
root hair cells the process of osmosis from the soil.
They have many mitochondria that transfer the energy
needed for active transport of mineral ions.
Xylem cells are alive when first formed but a chemical
called lignin builds up in spirals in the cell walls. The
Give 2 adaptions of xylem cells die and form hollow tubes that transfer water
cells and mineral ions.
The spirals of lignin in the xylem cells make them very
strong to help them withstand pressure.
