What are adaptations?
To maximize their chances of survival, plants and animals have evolved special features called adaptations.
Some of these adaptations are found in many plant and animals species, but there are a few adaptations which are unique to a particular species.
Types of adaptations
Types of adaptations
There are three types of adaptations:
Structural adaptations:
Is the way in which a plant or animal has physically evolved. E.g. Types of skeleton, number of legs, size of body, structure of the mouth parts etc. and for a plant this includes, leaf size and shape, flower and seed type.
Physiological adaptations:
Is the chemical reactions that an organism can carry out, e.g. plants photosynthesize; both plants and animals undergo respiration; animals and some unusual plants digest food; etc.
Behavioural adaptations
Refers to the behaviours a plant or animal has evolved to help it survive.- to find food or a mate, or to avoid predators. For example, possums 'freeze' to avoid being seen by predators; climbing plants use structures such as trees or walls to help them reach sunlight.
