Plant and Animal Cells

1. Plant and Animal Cells Presented by Kesler Science

2. Essential Questions: What is the difference between structure and function in plant and animal cell organelles? What is a cell membrane, cell wall, nucleus, cytoplasm, mitochondria, chloroplast, and vacuole ?

3. Plant and Animal Cells Plant and Animal Cells All eukaryotic cells (has a nucleus) in which all the organelles are contained in membranes. Animal Plant So what makes them different?

4. Plant and Animal Cells Organelle • Tiny cellular structure that performs specific functions within a cell. • Similar to the way the body’s organs perform different functions.

5. Quick Action – INB Template Plant and Animal Cells INB Template • Cut out the Template • Glue the template into your notebook along the thin tab. • You can organize this with the next 3 templates to make a flip book. • Fill in the names of the cell organelles.

6. Plant and Animal Cells Animal Cell Organelles • Cell Membrane • Nucleus • Cytoplasm • Mitochondrion • Vacuoles (sometimes) Cytoplasm Mitochondrion Nucleus Vacuoles Cell Membrane

7. Quick Action – INB Template Plant and Animal Cells INB Template • Cut out the Template • Glue the template into your notebook making a flip book. • Fill in the names of the cell organelles.

8. Plant and Animal Cells Vacuoles Plant Cell Organelles • Cell Membrane • Cell Wall • Nucleus • Cytoplasm • Mitochondrion • Vacuoles • Chloroplast Cytoplasm Cell Wall Nucleus Cell Membrane Chloroplast Mitochondrion

9. Quick Action – INB Template Plant and Animal Cells INB Template • Cut out the Template • Glue the template into your notebook along the thin tab. Add to your flipbook. • Explain the function of each organelle.

10. Quick Action – INB Template Plant and Animal Cells INB Template • Cut out the Template • Glue the template into your notebook along the thin tab. Add to your flipbook. • Explain the function of each organelle.

11. Plant and Animal Cells Cell Wall • Found in plant cells only • Rigid, strong, stiff outer layer • Supports the plant (allows it to grow tall) • Protects the cell • Allows water, oxygen, and carbon dioxide to pass into and out of the cell.

12. Plant and Animal Cells Cell Membrane • Found in both plant and animal cells • Plant – inside the cell wall • Animal – outer layer • Supports and protects the cell • Controls movement of materials in and out of the cell • Maintains homeostasis (condition of balance)

13. Plant and Animal Cells Nucleus • Found in both plant and animal cells • Large, oval shape in the center of animal cells and at the edge of plant cells • Controls cell activities (the brain) • Controls hereditary materials Animal Plant

14. Quick Action – Plant and Animal Cells Get with a friend and look at the pictures of animal cells and plant cell with their nucleus. Sketch each type of cell and answer these questions. What is the main difference you see in the two types of cells? Why do you think plant cells need a cell wall as well as a cell membrane? What would happen to plants if they did not have a cell wall? Plant Animal

15. Plant and Animal Cells Cytoplasm • Found in both plant and animal cells • Clear, thick jelly like material • Supports and protects cell organelles

16. Plant and Animal Cells Mitochondrion • Found in both plant and animal cells • Bean-shaped with inner membranes • Breaks down sugar molecules into energy (ATP - the chemical energy of the cell) • “Power House” of the cell

17. Plant and Animal Cells Plant Vacuole • Found in all plant cells (large) • Store large amounts of food (sugars) and water • Sometimes found in animal cells (few and small) • Store food, water, metabolic and toxic waste • Fluid-filled sacs Vacuole Animal

18. Plant and Animal Cells Chloroplast • Found in plant cells only • Green, oval • Contain chlorophyll (green pigment) • Uses energy from the sun to make food (sugar and oxygen) for the plant (photosynthesis).

19. Quick Action – INB Template Plant and Animal Cells INB Template • Get with a friend to fill in the Venn Diagram. • When you have finished , cut out the Template. • Glue the title and Venn diagram into your notebook.

20. Check for Understanding Can you… • Tell the difference in the structure of plant and animal cells ? • Tell the difference in the function of plant and animal cell organelles, including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast and vacuole?
