1. All organisms (living things) are made of cells
a. All of these cells are composed of chemicals
2. All organisms (at least their cells) use energy
3. All organisms grow and develop
4. All organisms respond and may adopt to their environment
5. All organisms can reproduce
6. All organisms get rid of wastes
1. Energy
2. Water
3. Homeostasis (stable internal conditions such as heartbeat and temperature)
4. Living space
There are really five characteristics of an organism.
- Using Energy
- Responding to Environment
- Growing and Developing
- Being made of at least one cell
- Having the ability to reproduce
Living things: are chemically unique meaning they will contain nucleic acids, proteins, carbohydrates, and lipids; will consist of one or more cells; extract/store/transform energy; share a genetic code; reproduce; evolve, must maintain homoeostasis; have hierarchy in internal and external environment.
