Unit 3: Cells



Cell Organelles






Relevant Science Standards:

SB1. Students will analyze the nature of the relationships between structures and functions in living cells. 
        a. Explain the role of cell organelles for both prokaryotic and eukaryotic cells, including            the cell membrane, in maintaining homeostasis and cell reproduction. 
        d. Explain the impact of water on life processes (i.e., osmosis, diffusion).

6. What is the function of the cell membrane? 
7. What is the difference between passive and active transport? 
8. What variables affect the rate of transport across a membrane? 
9. Why is it important that cell membranes are selectively permeable? 
10. How does a cell maintain homeostasis both within itself and as part of a multicellular organism?
