Cell Structure and
Cell structure and function
| Question | Answer |
|---|---|
| Cell | Basic unit of Life |
| Cell Theory | fundemental concept of biology |
| Nucleus | a large membrane-enclosed structure that contains the cell's activities |
| Eukaryotes | Cells with a nuclei |
| Prokaryotes | cells without a nuclei |
| Organelle | Little organs |
| Cytoplasm | The portion of the cell out side the nucleus |
| Nuclear Envelope | Layer of two membrane that encloses the nucleus of a cell |
| Chromatin | granular material inside a nucleus |
| Chromosomes | Condense chromatin after the cell divides |
| Nucleolus | small dense region inside the nucleus |
| Ribosomes | makes proteins |
| Endoplasmic Reticulum | an internal membrane systemin a Eukaryotic cell |
| Golgi Apparatis | modifies, sorts, and packages proteins |
| Lysosomes | small organell filled with enzymes |
| Vacuoles | stores minerals such as water,salts,proteins, and carbohydrates |
| Mitochondria | convert chemical energy stored in food |
| Chloroplasts | capture the sun's energy and convert it to chemical energy |
| Cytoskeleton | supporting structure of a cell |
| Centrioles | help organize cell division |
| Cell Membrane | thin flexible barrier surrounded the cell |
| Cell Wall | strong supporting cell membrane |
| Lipid Bilayer | double-layered cell membrane |
| Concentration | The mass of a given solute in a given volume of solution |
| Diffusion | A more concentrated area moves to a less concentrated area? Spread Out evenly |
| Equlibrium | When concentration of the solute is the same everywhere |
| Osmosis | water can pass easily through cell membrane when other stuff can't |
| Isotonic | when water and sugar is the same on both sides |
| Hypertonic | when sugar is more concentated than water |
| Hypotonic | Sugar is less concentrated than water |
| Facilitated Diffusion | Where molecules move through protein channels |
| Active Transport | moving molecules in the opposite direction |
| Endocytosis | Taking molecules into the cell by having pockets they fall in or other little tricks |
| Phagocytosis | cytoplasm surroundes a paticle into a food vacoule |
| Pinocytosis | Tiny pockets form along the cell membrane |
| Exocytosis | The membrane of a vacule sorroundng the material fuses with the cell membrane, forcing the contents out of the cell |
| Cell Specialization | cells develope different ways to perform tasks |
| Tissue | Similar cells grouped into units |
| Organ | tissues work together to form an organ |
| Organ system | a group of organs form a organ system to perform a certain function |
