1. Made of one or more cells

The Cell is the basic structural and functional unit of all life.

Unicellular (one cell)

- ex. Bacteria

Multicellular (many cells)

- ex. Animals, plants

2. Sense and respond to change (stimuli in their environment)

Stimuli - factors in the environment that living things react to

(ex. Light, temperature, sound, etc.)

Organisms react in order to maintain Homeostasis

3. Reproduce Sexual - two sex

cells required (sperm and egg)

Asexual - only one parent cell is needed

4. Have a universal genetic code – RNA or DNA (Chemicals of Life)

All living things have Chemicals of Life

Long molecules that contain genetic information

Passed on from one generation to the next

5. Use energy to survive – 2 ways

Autotrophs/Producers - get energy from sun

Heterotrophs/Consumers - get energy by consuming other organisms

6. Grow and Develop

Cell division for growth

Development through cell specialization
