| Characteristics of Living Things | Cellular Organization, Contains similar chemicals, Uses Energy, Growth and Development, Responds to Surroundings, Reproduction |
| Reproduction | Produces offspring similar to parent; like produces like |
| Response to Surroundings | Respond to stimuli |
| Stimulus | Change in environment/surrounding (ex. temperature, light, and sound) |
| Response | Reaction to specific stimuli (ex: sweat, grow toward light, turn head toward sound) |
| Growth | Increasing in size |
| Development | Changes that result in more complex organism (ex. acorn to adult oak tree) |
| Use Energy | Needed for growth and repair of damanged cells |
| Similar Chemicals | Water, Carbohydrates, Proteins, Lipids, Nucleic Acids |
| Cellular Organization | Building Blocks of Life; unicellular - 1 celled; multicellular - many cells |
| Spontaneous Generation | Mistaken idea that living things came from non-living things |
| Needs of Living Things | Energy, Water, Living Space, Stable Internal Conditions |
| Energy | Autotrophs - make own food from sun's energy; Heterotrophs - rely on autotrophs or other heterotrophs to get energy |
| Water | Needed for chemical reactions; dissolves most chemicals |
| Living Space | Place to get food, water, shelter |
| Stable Internal Conditions | Homeostasis |
| Homeostasis | Constant body temperature; Warmblooded (automatic), Coldblooded (stick shift) |
| Cell Theory | All living things composed of cells; Cells are basic unit of structure and function in living things; All cells are produced from other cells |
| Early Atmosphere of Earth (Theory) | Nitrogen, water vapor, carbon dioxide, and methane |
| Early organisms (Theory) | Thought to not need oxygen |
