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