  1. What are the six most important life processes?
    • •Metabolism
    • •Growth
    • •Differentiation
    • •Reproduction
    • •Movement
    • •Responsiveness
  2. Describe metabolism and its two phases.
    • •Metabolism is the sum of all the chemical processes in the body. 
    • •Metabolism has two phases: catabolism and anabolism.
    • •Catabolism is the breaking down of complex chemicals into smaller, simpler structures.
    • •Anabolism is the building up of complex chemical substances from smaller, simpler ones.
  3. Describe responsiveness.
    Responsiveness is the body's ability to detect and respond to changes. 

    ie: Body temp rising during a fever, or turning your head towards sounds.
  4. Describe movement.
    Movement includes movement of the entire body, including organs, single cells, and even tiny structures in cells.
  5. Describe growth.
    Growth is an increase in body size that results from an increase in size of existing cells, the number of cells, or both. In addition, growth in tissue can also result from the addition of material between cells.
  6. Describe differentiation.
    Differentiation is the development of a cell from an unspecialized state to that of a specialized one. The precursor cells are known as stem cells.
  7. Describe reproduction.
    Reproduction refers to either the formation of new cells for tissue repair, growth, or replacement, or the production of a new individual.
  8. What happens when any one of the life processes eases to occur properly?
    Death of cells and tissue which may result in the death or the organism
