1. Adaptations of Plants
Xerophytes and Hydrophytes

2. Adaptations of Plants
 Plants can survive in many extreme
environments.
 Xerophytes – Desert Plants
 Hydrophytes – Water Plants (live in ponds,
rivers and swamps)
 In order to survive in these environments,
these plants need to have adaptations.

3. Xerophytes

4. Xerophyte Adaptations
 Well established root
systems.
 Grow deeply and in all
directions in order to
anchor the plants in
sandy soil and against
the wind.
 Helps to maximize water
uptake.

 The cooler

plant to take up CO2
through their stomata
without sacrificing
water.

8. Hydrophytes

9. Adaptations of Hydrophytes
 Have lots of air spaces
in their tissues.
 This helps them to float
in water.

10. Adaptations of Hydrophytes
 Roots in water-
clogged soil are called
‘Breathing Roots’ or
‘Pneumatophores’.
 These roots grow to
reach the surface
above the water in
order to obtain CO2 to
survive.
 Marshes or Swamps

 Again, if you were in that environment, what
would you need to survive?
 To breathe underwater?
 To float on the water?
