Biology Adaptation

Adaptation Definition: Adaptation is the process of how organisms develop special structures and internal processes to enable them to live in their environment. Definition: Adaptation is the process of how organisms develop special structures and internal processes to enable them to live in their environment. Organisms can be adapted in two ways: 1. Body structure (e. g. Small ears to reduce heat loss) 2. Body processes (e. g. Osmoregulation in salmon)General Biology Ii Study Guide (Online Class)There are several factors which cause adaptation to occur: Physical Factors * * * Other organisms * * * Adaptations Match the following animals to the adaptations below, and suggest why they are useful.

Marram grass is a good example of a plant which is adapted to live in very dry conditions, for example on sand dune systems. The leaves of the marram grass are adapted to survive with the limited water available in the desert. Read also Lab 2 BiologyIn very dry conditions, the leaves of the marram grass roll up to form long tubes. This helps drain any water down towards the roots of the plant. Match the adaptations of the marram grass leaves with their function Waxy CuticleReduce water loss through transpiration Stomata sunk in pitsTrap a layer of moist air close to the leaf surface Leaf HairsProtects the stomata from the wind, reducing water loss through evaporation Rolled LeafReduces water loss through evaporation
