Explain how aquatic and terrestrial plants are adapted to deal with problems of transpiration

a. Mesophytes
b.Xerophytes
c.Hydrophytes

Answers

Isacko
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
