Biology HS/Science Unit: 04 Lesson: 01 Viewing Cells KEY 1. Who first saw and named cells? Why are they named cells? Robert Hooke first saw cells and named them that because they looked similar to the rooms of monks. 2. Were the bacteria larger or smaller than the other cells? The bacteria appeared smaller than the other cells. 3. Did the protist cells appear more like bacteria, plant, or animal cells? Explain your answer. Some protists appear like plant cells (Euglena) because they are green. Other protists appear like animal cells (Amoeba). 4. In your drawings of plant and animal cells, what structures did you notice that were different? Explain your answer. Student answers will vary, but should include something similar to this: The plant cells appeared more rigid and boxy on the edges (cell wall) and they also had green structures (chloroplasts). 5. In the plants cells you observed, all the cells had a similar shape. The cheek cells were more irregular in shape. Explain why you think the shapes might be different. The plant cells have a cell wall; the animal cells do not have a cell wall. Plant cells are more rigid to support the plant’s shape. ©2012, TESCCC 08/15/12 page 1 of 1
