Organisms and their Adaptations, marram grass has curved leaves which can…

- - - - Leopards have spots which camouflage them in dappled light. This helps them to hide from their prey
  - - - Hydrophyte leaves: they have a very thin or no waxy cuticle. many always open stomata on the surface of the leaf. They have very little lignin in the leaf as they are supported by water . they have wide flat leaves to capture sunlight,
    - - Small reflective hairs, normally white or grey, on desert plants which allows light to be reflected away from the plant and prevents excess transpiration eg. Echeveria
    - - Prickly pear cactus - has a thick fleshy stem which allows water to be held out of the sun to reduce transpiration.
    - - Stilt roots- provide support to trees with shallow roots as the nutrients are shallow in the soil in a rainforest.
      - Marram grass has some metre long roots that extend directly down towards moisture. They also have creeping stems called rhizomes that extend widthways below the surface which more lengths of roots grow off to extend coverage and give support.
- - - - Sand gazelles' bodies allow them to breathe less by shrinking their heart and liver, causing prevention of moisture loss and retaining water in their system. Sand gazelles are also able to absorb urine and reuse it as a water source, in small amounts back into their body.
