1. Which characteristic is shared by all prokaryotes and eukaryotes? Ability to store genetic information Use of organelles to control cell processes DNA that is free floating in the cell Both types of cells are a similar size

2. Which two structures are common to both prokaryotes and eukaryotes? Cell membrane and nucleus Cell membrane and choloroplasts Cell membrane and cytoplasm Cell wall and cytoplasm

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

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

5. Which of the following equations best represents the endosymbiotic theory? Prokaryote + Eukaryote = Eukaryote Eukaryote + Eukaryote = Prokaryote Prokaryote + Prokaryote = Eukaryote Prokaryote + Eukaryote = Prokaryote

6. Which of the following do NOT make up the cell membrane? Carbohydrate Lipid DNA Protein

7. The cell in the box is pictured in a __________ solution. 10% salt 2% Hypertonic Isotonic Hypotonic Sugar

8. How will the water move in the picture of the cell below? 10% salt 2% Primarily into the cell Primarily out of the cell In and out of the cell at the same rate It won’t move

9.Facilitated diffusion occurs when… Molecules move from a high to low concentration across the lipid bilayer Molecules move from a low to high concentration across the lipid bilayer Molecules move from a high to low concentration through a protein channel Molecules move from a low to high concentration across a protein channel

10. The picture below best represents… Simple Diffusion Osmosis Facilitated Diffusion Active Transport

Test on MONDAY! What to study: Prokaryote vs Eukaryote Cell Theory Endosymbiotic Theory Cell membrane (parts & functions) Hypertonic, Hypotonic, Isotonic Molecule Transport (Osmosis, Diffusion, Facilitated Diffusion, Active Transport) **HOMEWORK VIDEOS are a GREAT tool for review!!

Review Day Today’s Goal: Answer all the review questions correctly (to prepare for Monday) and figure out the bonus! What to do: Get a partner Start at any question, read it, answer it correctly, circle the letter it tells you to circle. Figure out the bonus after answering all the questions. Turn in your paper when you are done…YES, it is a grade 
