1. Characteristics of Life

2. Living things are based on a universal genetic code
The code is written in a molecule called DNA

3. Living things grow and develop
Growth is increase in mass
Development is change in structure

4. Living things respond to their environment
Organisms detect and react to stimuli

5. Livings things reproduce
Reproduction can be sexual or asexual

6. Living things maintain a stable internal environment
Homeostasis (same state)is a stable, internal condition
Examples include temperature, fluid balance (amount of water), and pH

7. Living things obtain and use material and energy
The combination of chemical reactions through which an organism builds up or breaks down materials is metabolism

8. Living things are made up of cells
Cells are the smallest units of life

9. Taken as a group, living things evolve.
Evolution is change in a population over time. It does not occur in individual organisms.

10. Summary! Living things…..
Are based on a universal genetic code
Grow and develop
Respond to their environment
Reproduce
Maintain homeostasis
Use material and energy
Are made of cells
Evolve, as a group
