Characteristics of Life
Life is -
1 - Made up of cells
Cells are the basic unit of life. Living things are composed of cells.
2- Cellular Organization
Living things are able to organize simple things into complex things. Humans can organize cells that are alike into tissues and organs.
3 - The Chemicals of Life
Living cells are composed of similar chemicals, water, carbohydrates, proteins, lipids, and nucleic acids.
4 - Energy Use
Living things use energy to repair and function -- your brain cells are using energy right now.
5 - Response to Surroundings
Living things react to changes in environment. Populations evolve over time. You respond to your surroundings when you are startled by a car horn.
6 - Growth and Development
Living things grow from the energy found in organic molecules and develop, becoming more complex over time.
7 - Reproduction
Living things duplicate their genetic code and produce offspring.
