Let’s see how much you’ve picked up with these experiments and the reading – answer as best as you can. (No peeking at the answers until you’re done!) Just relax and see what jumps to mind when you read the question. You can also print these out and jot down your answers in your science notebook.

1. Why are cells called the “building blocks” of life?
2. Anton van Leeuwenhoek discovered animals no one had ever seen before. How was he able to do this?
3. You leave some bread on your counter. After a few days, you notice some mold growing on the bread. According to the cell theory, where did the cells that make this mold come from?
4. How does the shape of a nerve cell help it do its job?
5. If a cell had no cell membrane, what might happen to it? Why?
6. Where are the organelles found in a cell?
7. If a cell was making proteins, but the proteins were not the type the cell needed, what organelle is most likely not working properly? Why?
8. How are prokaryotes different from eukaryotes?
9. What are three places ribosomes are found?
10. How is the endoplasmic reticulum like a freeway?
11. What might happen in a cell if the Golgi Apparatus was not working properly?
12. What does the mitochondrion do in the cell?
13. How are vesicles and vacuoles similar? How are they different?
14. Name two organelles found in plant cells, but not animal cells.
15. What might happen to a plant if its cells didn’t have cell walls?
16. Thinking about the organelles they have, why can’t animals undergo photosynthesis?
17. Imagine that the wall of a dam breaks, and water begins rushing through the hole in the wall. Explain this in terms of concentration.
18. Nutrient X has a higher concentration inside a cell than outside a cell. Will active or passive transport be required to get nutrient X into the cell? Explain.
19. Is it possible for a protein to assist something cross the cell membrane, and have it still be considered passive transport? Explain.
20. Why is photosynthesis important to plants? Why is it important to animals?
21. Your friend tells you that photosynthesis “creates” energy for plants. How would you correct this statement?
22. How is glucose used differently than ATP in the cell?
23. What is the purpose of cellular respiration?
24. Name two types of cell division used by prokaryotes.
25. Why does the nucleus need to break down during mitosis?
