2. Characteristics of Living Things

3. 1. All living things are made of cells;
The basic units of structure and function in all living things
unicellular (one celled organisms)
multicellular (more than one cell)
Cells have different functions, but they all work together to enable the individual to live and survive in its environment.
Red Blood cells
Onion skin epidermal cells
Human cheek cells

through the processes of:
Metabolism
Ingestion
Digestion
Respiration
Excretion
Energy powers life processes. It provides organisms with the ability to grow, reproduce and carry out other life functions.

6. 4. All living things grow and develop.
*Increase in cell size and/or number
*Life Cycle- Birth, growth, reproduction, death.
*Life Span- The maximum amount of time a particular organism is expected to live.

7. 5. All living things respond to their environment.
Living things respond to internal or external stimuli (changes) in their environment. Living things react to touch, light, heat, cold and sound along with signals from inside their bodies.
Stimulus (signal) Response (action)
