BIOLOGY Unit 2: What is the Structure of Life? ESSENTIAL QUESTIONS 1. Why is the cell the basic unit of life? 2. How does the structure of a cell serve its function? 3. What similarities & differences exist between cells of different organisms and WHY? 4. Why do cells need and outside & an inside? 5. How do cells maintain homeostasis? WHEN YOU FINISH THIS UNIT YOU SHOULD BE ABLE TO…. 1. Define, use correctly, and give/recognize examples of each of the vocabulary words. 2. Understand the relative sizes of different cells. 3. Understand that the shape (structure) of a cell is directly related to its function & be able to give examples. 4. Identify the structure and function of the different organelles found in eukaryotic cells. 5. Understand the difference & similarities between the different cells of organisms from each Kingdom. 6. Be able to use a microscope to identify different types & parts of cells. 7. Describe the structure of the cell membrane & its importance in regulating a cell. 8. Understand the importance of proteins & lipids in the cell membrane. 9. Understand the importance of the cell membrane in maintaining homeostasis. 10. Identify the different mechanisms the cell uses to transport materials into & out of a cell based on the type of molecule needing to pass. 11. Relate diffusion to equilibrium. 12. Relate osmosis to solute concentration. 13. Understand the relationship between cell size, cell transport & energy efficiency.
