Plant distributed in different habitats of
aquatic ,moderate and dry condition

Adaptation
Remove excess
water by
 large surface area
of leaf
 extensive stomata
on upper surface of
leaf

15. Mesophytes
Plant that live in moderate condition
Examples
Mango
Brassica
Rose
Adaptation
Sufficient water
supply
Restricted water
 supply
Stomata open
Stomata close

16. Xerophytes
Plant that live in desert or dry condition

Small,thick
Shed leaf (driest season)
Cuticle
Thick,waxy,leathery
Stomata
On lower surface
Located in depression
Stem
