6. Multicellular Organisms

7. Multicellular organisms Organisms that are made up of many cells that work together. Have cell specialization

8. Multicellular organisms Organisms that are made up of many cells that work together. Have cell specialization –Cells only perform particular specialized functions within the organism Examples?

9. Multicellular organisms Organisms that are made up of many cells that work together. Have cell specialization –Cells only perform particular specialized functions within the organism Examples? RBC, nerve cells, muscle cells, pancreatic cells

10. Multicellular organisms Organisms that are made up of many cells that work together. Have cell specialization –Cells only perform particular specialized functions within the organism Examples? RBC, nerve cells, muscle cells, pancreatic cells -cells contain variety of organelles based on function
