Characteristics of Living Things Life Science Objectives  Be able to determine whether something is a living thing or a non-living thing.  Learn and understand the 5 main characteristics of living things. (ROGER) There are 5 Characteristics of Living Things 1. Respond 2. Organization (CELLS) 3. Growth & Development 4. Energy 5. Reproduction ROGER R Respond Living things respond to their environment.  Stimulus: anything that causes a change in an organism. Causes the organism to react Response: a reaction or change in behavior due to the stimulus.

White blood cells Red blood cells Cardiac muscle cell ROGER Grow and Develop  Growth: Unicellular organism  increase in cell size.  Multicellular organism increase the number of cells.
