Characteristics of Living Things 1) Lifespan Individuals have a specific lifespan, grow old and eventually die. 2) Grow, Reproduce and Repair living things all grow in size, produce offspring and repair injuries 3) Respond to environment living things respond to environment ex. predators, moisture, sunlight 4) Require Energy obtain energy from other organisms or sunlight (plants)
5) Waste living things produce unwanted materials that they release to the environment Cell Theory 1) All living things are composed of one or more cells 2) The cell is the basic unit of life 3) All cells come from pre-existing cells To do now
