Movement
An action by an organism or part of an organism causing a change of position or place
Respiration
The chemical reactions that break down nutrient molecules in living cells to release energy for metabolism
Sensitivity
The ability to detect or sense stimuli in the internal or external environment and to make appropriate responses
Homeostasis
This is the control of internal conditions to provide the optimum conditions inside cells for all the reactions needed for life
Growth
A permanent increase in size and dry mass by an increase in cell number or cell size or both
Reproduction
The processes that make more of the same kind of organism
Excretion
The removal from organisms of toxic materials, tje waste products of metabolism and substances in excess of requirements.
Nutrition
The taking in of materials for energy, growth and development. Plants require light, carbon dioxide, water and ions. Animals need organic compounds, ions and usually need water.
