3. Organelles: 200 Question: What’s the best & second best way to distinguish between a prokaryotic and an eukaryotic cell? Answer Nucleus, Membrane-bound organelles

4. Organelles : 400 Question: What’s the best & second best way to distinguish between a plant and an animal cell? Answer Chloroplast, cell wall

5. Organelles : 600 Question: Name and identify the organelles involved in animal and plant metabolism Answer Mitochondria, chloroplast

6. Organelles : 800 Question: Animal metabolism (cellular respiration) happens in 3 stages: Glycolysis, Citric Acid Cycle, and the Electron Transport Chain. Which of these 3 stages takes place outside the mitochondria? Answer: glycolysis

7. Organelles : 1000 Question: Describe the organelles involved in protein synthesis and their role in the process from start to finish. Answer Nucleus (store DNA), Ribosome (translate mRNA), Golgi (protein modification)

8. Transport: 200 Question: Molecules diffusing across a membrane from high concentration to low concentration is what type of transport? Answer Passive Transport

9. Transport : 400 Question: Molecules being moved across a membrane from low concentration to high concentration is what type of transport? What does this type of transport require? Answer Active transport, energy

10. Transport : 600 Question: Simple diffusion directly across a membrane is possible with small molecules. What type of diffusion happens when larger molecules need the help of a transport protein? Answer Facilitated diffusion

11. Transport : 800 Question: A slice of potato is placed in a glass of highly concentrated salt water. Will the potato shrink or swell, and why? Answer Shrink- water moves to the higher concentrated salt water

12. Transport : 1000 Question: A slice of potato is placed in a glass of water with a solute concentration equal to that of the potato. Will the potato shrink or swell, and why? Answer Neither- equal concentration of solute so no osmosis.

13. Macromolecules: 200 Question: The macromolecule that makes up DNA. Bonus 200: What are the 3 parts of it? Answer Nucleotide; phosphate, ribose sugar, nucleic acid base

14. Macromolecules: 400 Question: A protein consists of chains of what? What determines a protein’s function? Answer Amino acids, its shape

15. Macromolecules: 600 Question: These macromolecules are used for short and long term energy storage (have to say which is which). Answer Carbs and lipids

16. Macromolecules : 800 Question: A person that does not get enough phosphates in their diet would have trouble producing which macromolecule? Answer Nucleic acids/DNA & RNA

17.
