Chapter 1 Common Characteristics of Life  composed of cells  highly organized  exchanges energy with the environment  responds to stimuli  reproduces itself  evolves over time  adapts to environment  maintains homeostasis 7 characteristics common to life 1. Cells and organization: organisms maintain an internal order – simplest is the cell 2. Energy use and metabolism: to maintain internal order, energy is needed. Energy is utilized in chemical reactions collectively known as metabolism 3. Response to environmental changes: organisms react to environmental changes to increase chances of survival 4. Regulation and homeostasis: organisms regulate cells and body to maintain homeostasis – relatively stable internal conditions
