1. Parts of a Cell

2. Cell Function Sheet Have your sheet ready to write notes in.
Read and understand each slide before going to the next.
The most important information is IN PURPLE.
Check off if the organelle is found in a plant cell, animal cell, or both.

3. What are the functions of the organelles?
LAPTOP/iPAD activity:
Go to class webpage,
Find this presentation for today’s date.
Read each slide together.
Take notes by filling in blanks on your sheet.
AFTER ALL NOTES ARE DONE, get your sheet of picture clues (from the basket on demo table) to cut out and glue in the appropriate box on your sheet.

4. Here come the organelles…!

5. Cell Wall Plant cells only
Give plants their shape, structure, support, and protection
Surrounds the cell membrane
Allows H2O, O2, and CO2, to pass in and out of the cell

6. Cell Membrane
A continuous, almost invisible structure surrounding the cell
Supports & protects the cell
Controls movement of materials in and out of the cell

7. Chloroplasts Plant cells only
Uses energy from the sun to make food for the plant through photosynthesis
Where photosynthesis takes place
Power generator for the plant
Give plants their green color

8. Cytoplasm The cell’s environment or inner space.
Mostly made of water and contains organelles
The jellylike material outside the cell nucleus.

9. Mitochondria
Powerhouse of the cell. Supplies energy that the cell needs.
Breaks down sugar molecules into energy
Need oxygen to make energy and give off carbon dioxide as waste

10. Nucleus
The cell’s computer, brain, or manager. Uses DNA to control the cell’s activity
Contains all the information the cell needs to do specific jobs, grow, and divide
Information is stored in DNA molecules
Contains the nucleolus which makes ribosomes
Determines what proteins will be made

11. Lysosomes
Cell’s recycler. Breaks down large food and digests old cell parts.
Contains enzymes which break down the proteins

12. Ribosomes Produces protein which is the Product of the cell
Cells need protein to survive and grow
Protein

13. Vacuoles Storage bubbles found in cells.
Much larger in plant cells. Store food or nutrients a cell might need to survive.
Store waste products so the rest of the cell is protected from contamination.

14. Golgi Bodies
Packs
Packs and carries proteins in little bubbles that separate and float into the cytoplasm.
Prepares the proteins for use or delivery outside the cell

15. Endoplasmic Reticulum (E.R.)
Transportation system of the cell. Carries material through the cell.
Rough ER has ribosomes attached to it so the proteins they make can be released directly into the ER for transport
Smooth ER collects things and contains them

16. Nuclear Membrane
Protects and guards the nucleus. Allows materials to pass in and out.
Keeps the DNA inside the nucleus
Allows other materials to pass in and out of the nucleus

17. OBSERVE The Differences between Animal & Plant Cells

18. Now get your sheet of pictures!
Protein
Cut out the symbols and glue them next to the correct cell part, to help you remember the function of the organelle. Hint: Go back to the slide to see which picture goes with it!

Answer Key
* Check if you have all the symbols in the right boxes.
* Check if the organelle is in animal cells, plant cells or both.
* Then quiz a partner about the function of each of these organelles, by taking turns and using your paper.

20. Clean-Up Directions
Shut down your laptop, or sign out on your iPad. Return your device. Put glue sticks back on the demo table. Check the floor for scraps, and throw out. View microscope specimens if you are all done!
