2. All Cells have…. Ribosomes - make protein for use by the organism. Cytoplasm - jelly-like goo on the inside of the cell DNA - genetic material Cytoskeleton - the internal framework of the cell Cell membrane - outer boundary of the cell, some stuff can cross the cell membrane.

3. Prokaryotic Cells Prokaryotes are very simple cells. Prokaryotic cells do not contain a membrane bound nucleus. Bacteria are prokaryotes. DNA of bacteria is circular. The word "prokaryote" means "before the nucleus"

5. Eukaryotic Cells Eukaryotic cells are more advanced cells. These cells are found in plants, animals, fungi, and protists (small unicellular "animalcules"). They have a true nucleus.

6. Eukaryotic Cells Eukaryotic cells have 4 main parts: – cell membrane - outer boundary of the cell – cytoplasm - jelly-like fluid interior of the cell – nucleus - the "control center" of the cell, contains the cell's DNA (chromosomes) – organelles - "little organs" that carry out cell functions

7. Organelles Nucleus

8. Organelles Mitochondria – Energy center or "powerhouse" of the cell. Turns food into useable energy (ATP)

9. Organelles Ribosomes – Make protein

10. Organelles Golgi Apparatus – Processes and packages proteins

11. Organelles Lysosome – Contains digestive enzymes, breaks things down

12. Organelles Endoplasmic Reticulum – Smooth ER - no ribosomes – Rough ER - ribosomes – Transports the proteins synthesized by ribosomes

13. Organelles Nucleolus – Located inside the nucleus, makes ribosomes

14. Organelles Vacuole – Stores water or other substances, plant cells contain a large central vacuole.

15. Organelles Chloroplast – Uses sunlight to create food, photosynthesis (only found in plant cells)

16. Organelles Cell Wall – Provides additional support (plant and bacteria cells)

17. Organelles Microtubules – Part of the cytoskeleton, function in support – Also make up cilia and flagella (cell movement)

18. Animal Cell

19. Plant Cell

20. Organelles with DNA? The Mitochondria and Chloroplasts have their own DNA

21. Cell Membrane Function: to regulate what comes into the cell and what goes out Composed of a double layer of phospholipids and proteins
