- Respiration: The chemical reactions in cells that break down nutrient molecules and release energy for metabolism
- Sensitivity: The ability to detect or sense stimuli in the internal or external environment and to make appropriate responses
- 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 type 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
