You will need to be able to: • list and define the characteristics of living organisms Click. Biology

There are 7 characteristics: • • Movement Respiration Sensitivity Growth Reproduction Excretion Nutrition Click. Biology

Movement • An action by an organism or part of an organism causing a change of position or place. Click. Biology

Respiration • The chemical reactions that break down nutrient molecules in living cells to release energy Click. Biology

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

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

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

Excretion • The removal from organisms of toxic materials, the waste products of metabolism (chemical reactions in cells including respiration) and substances in excess of requirements. Click. Biology

Nutrition • The taking in of nutrients which are organic substances and mineral ions, containing raw materials or energy for growth and tissue repair, absorbing and assimilating them. Click. Biology

Summary • • Movement Respiration Sensitivity Growth Reproduction Excretion Nutrition Click. Biology
