  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. 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

  5. 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

  6. Xerophyte Adaptations

  7. 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

  8. Hydrophytes

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

  10. 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 Adaptations of Hydrophytes

  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?
