1
Living vs. Non-living

• The Characteristics of Life

2
All Living Things

• Maintain Homeostasis
• Require energy for gas exchange and other
  activities
• Stimulus response
• Growth and Development
• Reproduce
• Are Composed of Cells
• Display Heredity

3
Cells

• Cells are the basic components of all living
  things. Some organisms are single-celled or
  unicellular (bacteria) and some organisms are
  multi-cellular (humans).
• Cell growth can include size of cells or number
  of cells.

4
Require Energy

• All organisms must maintain stable internal
  conditions while living in a constantly changing
  external environment. (Homeostasis)
• Energy to carry out activities such as
  respiration (gas exchange).
• All organisms must be able to obtain and use
  resources, grow, reproduce, and maintain
  homeostasis.

5
Reproduction

• Reproduction is sexual or asexual.
• Sexual reproduction involves two parents that
  combine their genetic material.
• Asexual reproduction involves only one parent and
  produces identical offspring.

6
Heredity

• Living organisms inherit traits from the parent
  organisms that created them.

7
Response to Stimuli

• A stimulus is a change in an organisms
  surroundings that causes them to react.
• All organisms respond to their environment.

8
Viruses

• Viruses are not plants, animals, or bacteria.
  They are not living.
• They do have reproductive abilities, but they
  only reproduce within a living cell.
• They have to have a host.
