Adaptations of Plants

Xerophytes and Hydrophytes

adaptations of plants1
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.
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.

Xerophyte Adaptations
xerophyte adaptations1
Short Life Cycles

Grow from seeds to mature plants, produce flowers, fruits and seeds in a short amount of time.

These few days can coincide with the few days of rain.

Thickened, Waxy Cuticle

Prevention of water loss because the cuticle prevents the water that the leaves already have from escaping due to the high heat and intense sunlight.

Xerophyte Adaptations
xerophyte adaptations3
Many desert plants are called C4 or CAM plants.

These plants only open their stomata in the dark at night.

The cooler temperatures allow the plant to take up CO2 through their stomata without sacrificing water.

What can help you to remember the adaptations?

Imagine you are in that environment. What would you need?

Xerophyte Adaptations
adaptations of hydrophytes1
Roots in water-cloggedsoil are called ‘Breathing Roots’ or ‘Pneumatophores’.

These roots grow to reach the surfaceabove 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?
