1. Specialization and interactions within cells and organisms

2. Specialization and interactions within cells and organisms
Choose a specialized cell on the human body (skin, liver, etc)
Explain how specific organelles contribute to the function of that cell
Choose one of following processes: Exchange of gases; Circulation of fluids; Digestion of food; Excretion of waste
Choose an organ that participates in the process you chose, and explain how its structure contributes to its function
Explain how the process you chose contributes to the overall functioning of the organism

3. Cooperative interactions are more efficient
Cells
plasma membrane, cytoplasm (organelles in eukaryotes) contribute to the overall specialization and functioning of the cell
Multicellular organisms
specialization of organs contributes to the overall functioning of the organism.
Example: Exchange of gases, circulation of fluids
Holtzclaw: 43, 223, (225 example, don’t need details),

4. Unicellular populations
population of unicellular organisms can be similar to those of multicellular organisms
These interactions also lead to increased efficiancy
