Waxy cuticles prevent the heat from the sun
evaporating
water from the
thin
leaves.
Xerophytic plants are adapted to reduce
water.
The leaves of xerophytic plants are
curled
and reduce the
exposed
surface area,
waxy
cuticles,
sunken
stomata and
hairs
to trap
water
vapour.
These adaptations reduce the
water potential
gradient.
