Six Characteristics of Living Things1. Composed of cells.2. Complex organization patterns 3. Use energy.4. Have stable internal conditions.5. Grow and change.6. Reproduce

1. All Living Things are Composed of Cells

Two types of cells:1. Prokaryotic Cells

Most are single- celled organisms

2. Eukaryotic Cells

called homeostasis.
