Plants vs. Animal Cells

1. Plants vs. Animal Cells

2. Do Now • What do you think is the most important organelle? Why, please explain your answer using science!

3. All Cells • All cells have three basic components: Cell Membrane, Nucleus, Cytoplasm. • Animal Cells have similarities to plant cells, but are different in a few ways. • Let’s look:

4. Plant vs. Animal

5. Plant Cells • Plant cells are different from animal cells. • Plant cells contain many of the same organelles you would find in an animal cell with the exception of a few key players • (1)Cell Walls and (2)Chloroplasts are found in plant cells and not animal cells.

6. Cell Wall • Cell Walls are only found in plant cells. • Cell walls are rigid structures made of cellulose (basically wood). • Cell Walls perform the following: • Protect the Cells • Give the Cells a Strong Shape • They provide support for the Cells

7. Cell Walls

8. Chloroplast • Chloroplast is essentially what makes a plant cell a plant cell. • Chloroplasts are filled with chlorophyll. • Chlorophyll creates food from solar energy for the plants, it also give plants their usual green color.

9. Chloroplasts

10. Vacuoles • I know, animal cells have vacuoles, but there is a difference between the two cells.

11. Plant Vacuoles • Plant Cells have one or two LARGE vacuoles. These vacuoles hold water for the cells.

12. Animal Vacuoles • Animal cell vacuoles are numerous, small, and contain water, food, and waste.

13. More Differences: • Animal cells use mitochondria for energy production. Plants primarily use chloroplasts to produce energy. • Animal cells tend to have many small vacuoles. Mature plant cells may have only one large vacuole. • Animals cells have lysosomes,but plant cells do not.

14. Cells & Energy • Cells get energy originally from the sun. • In plant cells, chloroplasts trap light energy and change it into chemical energy. • The chemical energy is stored in bonds between atoms of carbon, hydrogen, and oxygen. • Atoms are the basic unit of matter. Matter is anything that has mass and takes up space.

15. In your notebook, draw a Venn diagram to compare and contrast animal cells to plant cells • Animal Cell • Plant Cell

16. Conclusion • All cells have a cell membrane, nucleus, and cytoplasm. • Plant Cells have: Chloroplasts, Cell Walls • Both Plant and Animal cells have vacuoles, however, Plant cells have VERY LARGE vacuoles, while animal cells have many small vacuoles.
