What it means to be alive
All living things have cellular organization. Think of cells as puzzle pieces that make up all living things This means 2 things: 1.) Living things have at least 1 cell (remember some things are unicellular) 2.) If they are multicellular their cells work together
Living things exchange gases with the environment Examples: O 2 (Oxygen) - Humans take oxygen in from the air. Plants put oxygen into the air. CO 2 (Carbon Dioxide) - Humans put CO2 into the air. Plants take CO2 from the air.
All living things use energy Some organisms eat food to obtain their energy. Some organisms use sunlight to obtain their energy. HeterotrophsAutotrophs
All living things respond to the environment. Homeostasis - The process by which an organism responds to its internal or external environment Examples of homeostasis: Regulating body temperature Regulating blood, glucose levels
All living things grow, develop, and die.
All living things reproduce to survive.

Find 3 pictures of living things and 3 pictures of non- living things. Either out of a magazine, real photos or you can even draw them, put them into your composition notebook. Under each, list the characteristics the thing does or does not have that makes it alive or non-living. Bring them to class and be prepared to share with the class whether they are living things or non-living things and why.
