1. Eukaryotic Cell Organelles
Structure & Function
It’s a small, small, world…

2. The Big Picture

3. All Different Shapes and Sizes!
Eukaryotic cells are everywhere!

4. Cytoplasm Comprised of the cell organelles Found all over the cell
Semi-fluid: 70-90% water
Found all over the cell
Contained by the cell membrane

5. Ribosomes Site of protein synthesis
Can either be free in cytoplasm or attached to rough endoplasmic reticulum

6. Rough Endoplasmic Reticulum
Makes and transports proteins
Covered with ribosomes (therefore rough ER)

7. Smooth Endoplasmic Reticulum
Numerous functions including synthesis of lipids and steroids
Lacks ribosomes

8. Golgi Apparatus Consists of closely layered stacks of membranes
Modifies, stores, and ships products of the Endoplasmic reticulum (proteins)

9. Lysosome Digestive organelle in eukaryotic cells
Defend a cell from invading bacteria and viruses and break down damaged or worn out cell parts

10. Centrioles Found in animal cells Composed of microtubules
Involved in cell division
Used to pull chromosomes apart

11. Central Vacuole
A fluid filled sac used for storage of materials needed by the cell
Helps with cellular digestion
In plant cells the vacuole usually stores water and ions that are needed in the cell

12. Cell Wall Found in plant cells Provides protection for plant cells
Helps maintain cell shape

13. “The Colorful” Chloroplast
Found in plant cells (not animal)
Allows plants to produce food through the process of photosynthesis

14. “The Colorful” Chloroplast
Contains the pigment chlorophyll
This is what gives plants their green color
Contains a double membrane

15. “The Mighty” Mitochondria
Supply ENERGY to the cell
They are bean shaped and have two membranes

16. “The Mighty” Mitochondria
Purpose of these two membranes is for an increased surface area.
This helps in the production of ATP
Mitochondria have their own ribosomes and DNA!

18. Cell Membrane
Cells of all organisms are surrounded by a cell membrane. It is a thin layer of lipid and protein that separates the cells contents from its environment

19. Cell Membrane
Function: Controls what enters and exits the cell (the gatekeeper)

20. Nucleus Contains most of the cell’s genetic material
Control center for the cell
Surrounded by a double membrane called an nuclear envelope

21. Nucleus
Contains a nucleolus: a specialized organelle in the nucleus of cells; the site of ribosome production.

22. Cytoskeleton Fibers that provide structural support for the cell
Helps the cell move
