1. Page 98 2 points for having a flow chart with a stamp. – (no stamp = no points) – Late stamp is OK

2. Page 99 ½ point for having each picture titled. ½ point for having each magnification written in. 1 point per drawing – Deduct ½ point if it is not in color

3. Page 100-101 1. What observable characteristics can be used as evidence for classifying a specimen as a plant? In other words, what structures or features do you see that tell you the specimen you observed (elodea) was a plant? Chloroplasts and/or cell wall (½ pt)

4. 2. Are the chloroplasts you observed moving or stationary? Stationary (½ pt)

5. 3. Inside the mouth, cheek cells are joined together in a sheet. Why are they scattered here? These cells were swabbed and removed. (½ pt)

6. 4. How are the animal cells different from the plant cells you observed (list at least three differences)? They contain no chloroplasts, they don’t have a cell wall, they needed to be stained, they were scattered, etc. (½ pt)

7. 5. What is the relationship between plant cell structure and the ability of plants to stand upright? Plant cells contain cell walls and a large central vacuole that helps them stay rigid ( ½ point)

8. 6. Cheek cells do not move on their own, so you will not find two organelles that function for cell movement. Name these organelles. Cilia & flagella ( ½ pt)

9. 7. Were the cells you observed eukaryotic or prokaryotic? How do you know? Eukaryotic. They had a nucleus and were plant and animal cells. We were able to see them under the microscope ( ½ pt)

10. 8. Is the nucleus always found in the center of the cell? No. ( ½ pt)

11. 9. Why are stains such as methylene blue used when observing certain cells under the microscope? Some cells don’t have pigments or color and require a stain to highlight certain features. Staining helps differentiate between different parts of the cell (1 pt)
