-Six characteristics of living things- have cells, also contain similar chemicals, reproduce, grow and develope, respon to surroundings, use energy.
-Four Needs of Living things- water, energy, living space, and stable internal conditions.
-Unicellular- has one cell.
-Multicellular- has more than one cell.
-Autotroph- Automatically makes its own food.
-Hetertroph- does not make its own food.
-Homeostasis- stable internal living conditions.
-Aristotle’s classification- three groups: 1 can swim, 2 can fly, can walk, run, or crawl.
