Title: Levels%20of%20Cellular%20Organization


1
Levels of Cellular Organization
2
Multi-cellular Organisms
  • Multi-cellular Organisms made of more than one
    cell. Specialized cells work together to make
    tissues, organs, and organ systems.

3
Unicellular Organisms
  • Unicellular One celled organism. They must
    perform all activities within one cell. NO
    TISSUES, ORGANS, OR SYSTEMS!!

4
Unicellular vs. Multicellular
  • Similar
  • Carry on all characteristics of life.
  • Have the same MAIN cell parts as multi-cellular
    organisms. Mitochondria, vacuole, ER, nucleus,
    ribosomes, chloroplast, Golgi bodies, etc. Except
    nucleus in Arachebacteria and Eubacteria
  • Different
  • Cells in multi-cellular organisms have a specific
    job. Unicellular organism must carry on all
    characteristics of life in one cell.
  • 2. Multi-cellular organisms have tissues,
    organs, and organ systems. Unicellular organisms
    DO NOT.

5
Prokaryotic and Eukaryotic Cells
6
Which Organelle is Missing?
7
The Nucleus Whats so Special?
  • membrane enclosed organelle found in eukaryotic
    cells.
  • contains most of the cell's genetic material
    (DNA) for reproduction
  • The function of the nucleus is to control the
    cells protein production

Lost and Found Project
  • P. 6 in Science notebook
  • Concept Unicellular vs. Multicellular
  • Must include the differences between prokaryotic
    and eukaryotic cells
  • Must describe the function of the nucleus
  • Paragraphs are to be on the back of poster
