1. Cell Theory All organisms are made of one or more cells. The cell is the basic unit of all living things. All cells come from existing cells.

2. Cell membrane- protective barrier that encloses a cell. Cytoplasm- fluid inside of cell Cell membrane & Cytoplasm

3. Nucleus- Contains the cell’s DNA. Nucleolus- dark area inside the nucleus that begins to make ribosomes Nucleus

4. Endoplasmic Reticulum (ER)- system of folded membranes in which proteins, lipid and other materials are transported to other parts of the cell. Rough Endoplasmic Reticulum- Close to nucleus has ribosomes on it Smooth Endoplasmic Reticulum- lacks ribosomes Endoplasmic Reticulum

5. Ribosomes- organelle that makes proteins -smallest organelle Ribosomes

6. Mitochondria- The organelle in which sugar is broken down to produce energy. (ATP) “The mighty mitochondria” Powerhouse of the cell Mitochondria

7. Golgi Complex- membrane that surrounds (packages) substances inside the cells so it can move around the cell. Golgi Complex

8. Lysosomes- Organelle that digests food particles, waste, damaged cell parts, & foreign invaders Lysosomes

9. Vacuoles- Stores water and other liquids Vacuoles

10. Cell wall- rigid structure that supports the cell 2 2 Chloroplast- organelle which uses the energy from the sun, water & CO 2 to make sugar & O 2 Cell wall & Chloroplast Organelles found in plant cells
