6. 2. Which two structures are common to both prokaryotes and eukaryotes? A.Cell membrane and nucleus B.Cell membrane and choloroplasts C.Cell membrane and cytoplasm D.Cell wall and cytoplasm

7. 3. Why are prokaryotes smaller than eukaryotes? A.Because eukaryotes don’t have membrane bound organelles and prokaryotes do B.Because eukaryotes have membrane bound organelles and prokaryotes don’t C.Because they are unicellular D.Because they are multicellular

8. 4. Avoli are microscopic air sacks in the lungs of mammals. Which statement best describes how their structure allows the lungs to function properly? A.They increase the amount of energy transferred from the lungs to the blood. B.They increase the flexibility of the lungs as they expand. C.They increase the volume of the lungs allowing more oxygen to be inhaled. D.They increase the surface area of the lungs, allowing for more efficient gas exchange.

15. Complete the Transport foldable by the end of class. Fold the paper in half. Label each section a type of molecule transport – Diffusion – Osmosis – Facilitated Diffusion – Active Transport Complete the following for each: – At the top, write a definition in your own words for the transport (be sure to note if it uses energy or not) – Draw a picture across the membrane to represent the transport—use a book if you are confused. – Color your picture. – This is a grade!
