1. DE Science Elementary “5-Minute Prep” For Cells How Cells Work > Comparing Cells

2. Comparing Cells – The Big Ideas Plant cells have a rigid cell wall. Animal cells have a membrane. Plant cells contain chloroplasts, where photosynthesis takes place. Animal cells do not have chloroplasts and do not conduct photosynthesis. Bacteria cells have no nucleus, making them less complex than animal and plant cells.

3. Comparing Cells – Prior Knowledge Students will have knowledge of plants prior to this study. It will be helpful for students to use the Fun-damental, Seeing Cells. It will also help if they can:Seeing Cells Explain that all living things are made up of cells. Name the parts of animal and plant cells. Explain the functions of the parts of animal and plant cells.

4. Comparing Cells – Common Misconceptions All cells have nuclei. Reality: Bacterium cells and red blood cells of human beings are examples of cells that do not have a nucleus.

6. Comparing Cells – Instructional Ideas Read the passage, Animals and Plants-What’s the Difference?Animals and Plants-What’s the Difference? –Have students make a model of an animal cell and a model of a plant cell using materials in the classroom. –Ask students to label the parts. –Then, ask students to write a brief paragraph to be displayed with the models explaining the difference between animal and plant cells.

7. Comparing Cells – Instructional Ideas Watch the video segment, Cells With No Nucleus.Cells With No Nucleus –Ask students to search on the Internet to find examples of bacteria that are helpful and bacteria that are harmful. –Ask students to fold a sheet of paper in half. –On the top half of the paper ask them to draw a picture displaying types of bacteria that are harmful. –On the bottom, ask them to draw a picture or write about a type of bacteria that is helpful. –Share drawings with the class.
