The definitions (from the syllabus) - learn these!

Movement: An action by an organism or part of an organism causing a change of position or place (can be fast or slow as in plants).

Respiration: The chemical reactions that break down nutrient molecules in living cells to release energy

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

Growth: A permanent increase in size and dry mass by an increase in cellnumber or cell size or both

Reproduction: The processes that make more of the same kind oforganism

Excretion: Removal from organisms of toxic materials, the waste products of metabolism (chemical reactions in cells including respiration) and substances inexcess of requirements

Nutrition: Taking in of nutrients which are organic substances and mineral ions, containing raw materials or energyfor growth and tissue repair, absorbing and assimilating them
