Title: Living%20vs.%20Non-living


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.
