what are the 6 functions of cells | 1. Basic unit of life 2. protection and support 3. movement 4. Communication 5. Cell membrane 6. Inheritance |
Organelles | structures within a cell |
Cell membrane/Plasma membrane | surrounding structure of the cell |
Extracellular substance | Substances outside the cell |
Intracellular substance | Substances inside the cell |
Mosaic Model | studies molecules in the cell membrane |
Nucleus | Control center of the cell |
Nucleolus | The small center part on the Nucleus |
Rough ER | It has ribosomes on it and transport things around the cell. |
Smooth ER | does not have ribosomes and transport things around the cell |
Golgi Apparatus | packages and distributes proteins around the cell |
Lysosomes | gets rid of waste |
Mitochondrion | Produces energy |
Microtubules | provide support to the cytoplasm |
Cilia | short tiny hair like structure |
Flagella | long hair like structure |
Microvilli | Increase surface area |
Ribosomes | Where proteins are produced |
Cytoskeleton | gives structure to the cell |
4 ways molecules can pass through a cell membrane | • 1. Directly through • 2. Membrane channels • 3. Carrier molecules • 4. Vesicles |
solution | Solid, liquid, or gas consisted of one or more substances (Kool Aid) |
solutes | substance that is dissovled (kool aid mix) |
Solvent | the substance that does the dissolving (water) |
Diffusion | going from a area of high concentration to an area of low concentration ( perfume) |
concentration gradient | Is a membrane of the difference in the concentration of solute in a solvent. |
Osmosis | water going from high to low concentration |
Osmotic pressure | prevents movement and more molecules taking up space higher concentration on the left |
Hypotonic | high concentration of the solute inside the cell. (cell swells) |
Isotonic | equal of substances on each side of the cell |
Hypertonic | high concentration of water inside the cell (cell shrinks) |
Facilitated Diffusion | Larger Molecules use Carrier Protein to help them pass through the cell membrane. |
active transport | requires energy, low to high concentration |
Sodium potassium exchange pump | Pump used to move sodium and Potassium ions from areas of low concentration to high concentration. |
Endocytosis | material coming into cell membrane through veticles,entering |
Exocytosis | elmination of material from cell through vesicles, leaving |
Glycolysis | Anaerobic process during one glucose molecule is converted to two pyruvic acid molecules |
Aerobic Respiration | oxygen is present |
Anerobic respiration | oxygen is not present |
