Transcript and Presenter's Notes

Title: Diversity of Cellular Life


1
Diversity of Cellular Life
  • Unicellular vs. Multicellular Organisms

2
Unicellular Organisms
  • The cell IS the organism
  • Protists and Bacteria
  • They grow, reproduce, respond to environment, and
    maintain homeostasis
  • Colonial Organisms
  • Live together, but have no specialization

3
Multicellular Organisms
  • Made of many cells
  • Cell specialization
  • Cells are specialized to perform specific
    functions
  • Cells of same type work together
  • Can you name some different types of cells found
    in humans?
  • Red blood cells, nerve cells, muscle cells, etc.

4
Closer look at cell specialization
  • Red blood cells are designed to carry oxygen
  • Nerve cells are designed to carry impulses
  • Muscle cells are designed to promote movement

5
Multicellular Organization
  • Organ Systems (Digestive)
  • Organ (Stomach)
  • Tissue (Smooth muscle Tissue)
  • Specialized cells (Muscle cell)

6
Practice
  • Explain the levels of organization involved in
    touch
  • Nerve cells
  • Brain tissue
  • Brain
  • Nervous system

7
More practice
  • Explain the level of organization for 1 other
    type of cell found in the body
  • Construct an analogy that also shows different
    levels of organization (ex. School)
