Xerophytes and hydrophytes

  1. 1. Adaptations of Plants Xerophytes and Hydrophytes
  2. 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. 3. Xerophytes
  4. 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.
  5. 5. Xerophyte Adaptations Short Life Cycles  Thickened, Waxy  Grow from seeds to Cuticle mature plants, produce  Prevention of water loss flowers, fruits and because the cuticle seeds in a short prevents the water that amount of time. the leaves already have  These few days can from escaping due to the coincide with the few high heat and intense days of rain. sunlight.

  7. 7. Xerophyte Adaptations Many desert plants are  What can help you to called C4 or CAM remember the plants. adaptations?  These plants only open  Imagine you are in that their stomata in the dark environment. What at night. would you need?  The cooler temperatures allow the plant to take up CO2 through their stomata without sacrificing water.
  8. 8. Hydrophytes
  9. 9. Adaptations of Hydrophytes Have lots of air spaces in their tissues. This helps them to float in water.
  10. 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
  11. 11. Adaptations of Hydrophytes Again, if you were in that environment, what would you need to survive? To breathe underwater? To float on the water?
