a. Mesophytes
they grow in soils with enough water
water loss is perfectly balanced by absorption of more from the soil
no special adaptations
b. Xerophytes
they grow in dry conditions
root grow very deep to absorb water
succulent/?eshy leaves to store water
few stomata which are sunken
thickened waxy cuticle
leaves are hairy and often folding
some leaves are needle-like/spines or scales
leaf surfaces are reduced i.e. small leaves
all these adaptations are to reduce water loss
c. Hydrophytes
plants that grow in water
presence of sclereids
leaves are broad
leaves have many stomata on upper side only (none on the lower surface)
some leaves ?oat on water
absence or reduced leaf cuticle
large air spaces
some leaves are submerged
poorly developed or reduced vascular bundles
