1. Nucleus 2. Creates ribosomes 3. Creates proteins 4. Has a cell wall, chloroplast, and large central vacuole 5. Controls what enters and exits the cell 6. Golgi Body 7. Endoplasmic Reticulum 8. Where photosynthesis takes place 9. Powerhouse of the cell 10. Two organelles that make up the cytoskeleton

 The smallest unit of living matter  The theory behind cells ◦ All living things are made up of one or more cells ◦ Cells are the basic building blocks of life, provide structure and function ◦ All cells come from pre-existing cells.

 Prokaryotes ◦ cells with no nucleus ◦ lack other organelles ◦ unicellular ◦ simplest of cells ◦ can withstand extreme conditions

 Archaea

 Bacteria ◦ Alive ◦ Single cell ◦ Reproduce ◦ Good?  Yogurt  Fertilizer  Nitrites  Digestion ◦ Bad?  Strep Throat  Staph Infections  Tetanus  TB

 Eukaryotes ◦ cells with a nucleus ◦ membrane bound organelles ◦ comprise animals, plants and fungi ◦ often times comprise multicellular organisms

 Animal Cells

 Plant Cells

 Fungi Cells

 Not plant, animal or bacteria  Can’t live on their own  host cell  Can’t synthesize proteins  lack ribosomes ◦ Use host cell’s ribosomes  Can’t create own energy ◦ Use host cell’s  All viruses have DNA OR RNA  Examples ◦ HIV, Tobacco Mosiac Virus, Herpes ◦ H1N1, Measles
