There are 7 characteristics:

• Movement• Respiration• Sensitivity• Growth• Reproduction• Excretion• Nutrition

ClickBiology

Movement• An action by an organism or part of

an organism causing a change of position or place.

ClickBiology

Respiration• The chemical reactions that break

down nutrient molecules in living cells to release energy.

ClickBiology

Sensitivity

• The ability to detect or sense changes in the environment (stimuli) and to make responses.

ClickBiology

Growth

• A permanent increase in size and dry mass by an increase in cell number or cell size or both.

ClickBiology

Reproduction

• The processes that make more of the same kind of organism.

ClickBiology

Excretion

• The removal of toxic materials; the waste products of metabolism (chemical reactions in cells including respiration) and substances in excess of bodily requirements.
