S: Cells

FC: Cells | By: Trevor and Parker

1: Schlieden- All Plants are made of cells | Virchow- He called cells that because he studied them and he thought they looked like monk "cells" and named them after them | Hooke- He made the 1st microscope, also he contributed to seeing cells and studying them. | Schwann- He agreed with Schlieden that new cells were created from old cells

2: Prokaryotic | Prokaryotic cells do not have a nucleus.

3: Eukaryotic | Eukaryotic cells have a nucleus. An example of Eukaryotic cell is a Plant or animal cell.

4: Animal cells | 1. Nucleus 3. Round shape 5. Cytoplasm 7. ribosomes 9. occasional vacuole 11. no Plastids 13. no Cell wall 15. Microtubuals 17. lysosomes | 2. Cilla 4. No Chloroplasts 6. Endoplasmic Reticulum 8. Mitochondria 10. Centrioles 12. Golgi Apparatus 14. Plasma Membrane 16. Flagella

5: Plant cells | 1. Nucleus 3. Rectangle Shape 5. Cytoplasm 7. Ribosomes 9. BIG central Vacuole 11. Plastids 13. Cell Wall 15. Microfilaments 17. Lysosomes | 2. RARE cilias 4. Chloroplasts 6. Endoplasmic Reticulum 8. Mitochondria 10. Centrioles 12. Golgi Apparatus 14. Plasma Membrane 16. Flagella

6: Cytoskeleton: Composed Of Microtubules. Supports Cell Shape. Aids Movement of Matireals in and out of cells. | Endoplasmic Reticulum: Tubular network fused to nuclear membrane Goes through cytoplasm onto cell membrane Stores, separates, and serves as cell's transport system Smooth type: lacks ribosomes Rough type (pictured): ribosomes embedded in surface | Vacuoles: Membrane sacks for storage, digestion, and waste removal.

7: Cell | Mitochondria: Second Largest Organelle. Double layer membrane is where energy producting reactions happen controls resorces ia the cell Recycles protiens | Structure | Golgi Apparatus Protien "packing plant" Found near the nucleus. composed of numerous layers of membrane.

8: nuclear membrane: Surrounds the nucleus Made of 2 layers Numerous openings for nuclear traffic | Nucleolus: Spherical Shape Visible when cell is not dividing Contains RNA for protein manufacture | Lysosome: Digestive 'plant' for proteins, lipids, carbohydrates Transports undigested material for removal shape depends on process of being carried out. Cell breaks down if lysosome explodes

9: Cell Structures (cont.) | centrioles Paired cylindrical organelles near nucleus involved in cellular division Composed of nine tubes, each with three tubules Lie at right angles of each other | Ribosomes: Each cell contains thousands Make protein make 25% of the cell's mass Stationary: found on rough ER mobile. injects proteins directly into cytoplasm

10: Cell Membrane

11: The plant cell has not only a cell wall, but the also have a cell membrane, the cell wall is just extra protection. But, for animals, they have only the cell membrane, this means they don't have a certain structure like a plant cell.

12: Homeostasis | For it to maintain homeostasis the cell must maintain a constant internal environment and must be able to reproduce themselves when needed by the body.
