1. Parts of a Cell

2. Review - The Cell Theory
All living things are made of cells.
Cells are the basic units of structure and function in living things.
Living cells come only from other living cells.

3. Cell Organelles
Cells are made up of organelles, which are like tiny organs, each with its own job.
We can compare organelles to parts of a city, to understand the job the organelle does.

4. Organelles in an Animal Cell
Organelles in a Plant Cell
Organelles in an Animal Cell
What do all these structures do anyway??!!?

5. Cell Function sheet
The sheet, Cell Structures and Functions, has a chart with
Notes to write about all organelles found in animal and plant cells,
Columns to check off if it is found in an animal cell, or plant cell, or both.
A box for a picture clue of something found in a city to help remember the function.

6. Here come the organelles…!

7. 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

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

9. 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

10. 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

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

12. 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

13. 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

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

15. 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.

16. 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

17. 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

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