Plant cells vs. animal cells Next, we are going to focus specifically on two types of cells. Plant cells and animal cells have some important similarities and differences. But first, a quick review: –Are plants and animals prokaryotes or eukaryotes? –What does this mean about these organisms? –What does this mean about their cells? Please write your answers to these questions in your notebook. Contrasting Cases1

Plant cells vs. animal cells (cont’d) On the next slide, you will see two 3-dimensional drawings of cells. The one of the left is an artist’s interpretation of a plant cell. The one on the left is of an animal cell. These drawings represent cells that have had a portion cut away so the internal organelles can be visible. Please keep in mind that the colors used may not be the cell’s actual colors, and that lines drawn to label parts are not part of the actual cell being represented. These drawings are also drawn many times larger than a cell’s actual size. Please use the Venn diagram to write down the unique features of each of the cells, and also the ones they have in common.

Conclusions Now take a look at the web you created at the beginning of this lesson. –Please correct any incorrect ideas that you may have written down. –Please add new knowledge to your web. Why do plant and animal cells share some similar parts? Why do plant and animal cells have different parts? What similarities and differences are there between prokaryotic cells and eukaryotic cells? In conclusion, what is the one thing that is common to all living things? Contrasting Cases5
