Movement – an action by an organism or part of an organism causing change of position or place. 

Respiration – the chemical reactions in cells that break down nutrient molecules and release energy for metabolism. 

Sensitivity – the ability to detect sense stimuli in the internal or external environment and make appropriate responses. 

Growth – a permanent increase in size and dry mass by an increase in cell number, cell size or both. 

Reproduction – the processes that make more of the same kind of organism. 

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

Nutrition – taking in of materials for energy, growth, and development; plants require light, carbon dioxide, water and ions; animals need organic compounds and ions and usually need water. 


 Carl Linnaeus of Sweden, 1735 introduced the basis of modern taxonomy (classification). This groups organisms according to how closely related they are. This is called phylogenetic classification.
