2. Golgi apparatus Flat organelle Stores proteins to be distributed Pancake shaped layers

3. Ribosome Small structures that are the sites of protein synthesis in cells. Can be attached to ER (rough ER) or free floating in cytoplasm

4. Cilia Numerous hair-like extensions from plasma (cell) membrane Function to enable some cells to sense information in their surroundings

5. Nucleolus Structure found inside of nucleus that is responsible for making Ribosomes

6. Cytoplasm Thick fluid that fills cells (think toothpaste) Provides volume to cells and suspends cells parts

7. Flagella One or two relatively long extensions from plasma (cell) membrane Function as a propelier to help move some cells through watery environments.

8. Nucleus Control of the cell Has a double membrane Contains organelle that makes RNA Houses the DNA in the form of chromatin “Brain” of the Cell

9. Chloroplast Green organelle Contains chlorophyll Only in plant cells Site of photosynthesis

10. Mitochondria Organelle with double membrane Turns food into useable cell energy ATP Site of Cellular Respiration Found in Animal and Plant Cells “Powerhouse” of the Cell

11. Endoplasmic Reticulum Folded membrane Attaches to the Nucleus Can be covered in ribosomes Transports and packages proteins Smooth and Rough

12. Lysosome Contains digestive enzyme Digests wastes and old cell organelles Kills harmful bacteria and viruses Assists in the repair of the cell membrane

13. Cell Membrane Boundary of the cell Made of a type of lipids Surround plant and animal cells

14. Cell Wall Rigid boundary structure Found in Plants, Fungi, and Bacteria Provides structural support

15. Central Vacuole Stores water, wastes and nutrients for plants Can be the majority of volume of a plant cell
