Adaptations of Plants Xerophytes and Hydrophytes
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 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.

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.
Adaptations of Hydrophytes Have lots of air spaces in their tissues. This helps them to float in water.
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
Adaptations of Hydrophytes Again, if you were in that environment, what would you need to survive? To breathe underwater? To float on the water?
