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: What’s 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

9. 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
