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
