Cell Structure
| Question | Answer |
|---|---|
| Cytoplasm | Fluid portion of the cell outside the nucleus |
| Organelle | Specialized structure that performs important cellular functions within a Eukaryotic cell |
| Ribosome | Cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell; the site of protein synthesis |
| Endoplasmic Reticulum | Internal membrane system found in eukaryotic cells; where lipid components of the cell membrane are assembled |
| Golgi Apparatus | Organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell |
| Vacuole | Cell organelle that stores materials such as water, salts, proteins, and carbohydrates |
| Lysosome | Cell organelle that breaks down lipids, carbohydrates, and proteins, into small molecules that can be used by the rest of the cell |
| Cytoskeleton | Network of protein filaments in a eukaryotic cell that gives the cell it's shape and internal organization and is involved in movement |
| Chloroplast | Organelle found in cells of plants and some other organisms that captures the energy from the sunlight and converts it into chemical energy |
| Mitochondrion | Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use |
| Cell Wall | Strong, supporting layer around the cell membrane in some cells |
| Lipid Bilayer | Flexible, double layered sheet that makes up the cell membrane and forms a barrier between the cell and it's surroundings |
| Selectively Permeable | Property of biological membranes that allows some substances to pass across it while others cannot; also called semi permeable membrane |
