What Is a Cell?
1. Observe one prepared slide under the low-power lens of the microscope and then under the
high-power lens. Sketch the structures you observe under both lenses.
2. Repeat step 1 with the other prepared slides. With your partner, discuss and ask questions
about your observations.
Analyze and Conclude
1. Compare and Contrast What features do the cells you observed have in common? How
are they different from one another?
2. Use Models Study Figure 8-5, which shows different types of cells and some of their
structures. Which of these cells or structures do you think you observed and sketched?
3. Classify Review your sketches, and then classify the slides of cells into two or three
groups. Explain your classification scheme.
4. Ask Questions Pose questions based on your observations that would help you better
classify and identify the cells you studied.
