Chapter 3 (Cell)
| Question | Answer |
|---|---|
| Cell Membrane | Protect the cell |
| Nucleus | Control Center and contains the DNA |
| Nucleoli | Control Center of the Nucleus |
| Rough Endoplasmic Reticulum | ER with ribosomes attached to it |
| Smooth Endoplasmic Reticulum | ER for lipid synthesis in cells |
| Golgi Apparatus | Collects, modifies, packages, and distributes protein and lipids manufactured by the ER |
| Lysosomes | Contain a variety of enzymes that function as intracellular digestive systems |
| Mitochondria/on | Create ATP (energy) to the cell, by carrying oxygen |
| Microtubules | Help to support the cytoplasm of cells, assist the process of cell division, and form essential components of certain organelles such as cilia and flagela |
| Cilia | Present in cells that line the respiratory tract, moving mucus |
| Flagella | Propel the sperm cell |
| Microvilli | Work to increase the surface area of those cells |
| Ribosomes | where the proteins are produced |
| Cytoskeleton | proteins that support the cell |
| Organelles | Like a little organ in the cell, each one with a specific function |
| What is the 6 functions of the cell? | Basic unit of life; Protection and support; Movement; Communication (Message); Cell Metabolism and energy release; Inheritance |
| What are the four ways molecules can pass through the cell membrane? | 1. Directly through 2. Membrane channels 3. Carrier Molecules 4. Vesicles |
| Solution | Solid, liquid, or gas consisted of one or more substances |
| Solutes | Substance that is dissolved |
| Solvent | The substance that does the dissolve |
| Diffusion | Is the movement of molecules from the area of higher concentration to a area of lower concentration |
| Concentration gradient | Is a measure of the difference in the concentration of solute in a solvent |
| Osmosis | Is the process by which water molecules diffuse across a cell membrane |
| Osmotic Pressure | Is the pressure which needs to be applied to a solution to prevent the inward flow of water across the cell membrane |
| Hypotonic | When the molecules come from outside the cell to inside (have less molecules inside) |
| Isotonic | When outside and inside the cell have the same "quantity" of molecules |
| Hypertonic | When the molecules come from inside the cell to outside (have more molecules inside) |
| Facilitated Diffusion | When larger molecules use Carrier Protein to help them pass through the cell membrane |
| Active Transport | It a type of transport, but requires energy |
| Sodium potassium exchange pump | • 3 molecules of Sodium go in • Requires energy (ATP → ADP) • Go out (the sodium) • 2 molecules of Potassium go in • Go inside the cell (Potassium) |
| Endocytosis | When cells take in large particles/fluid |
| Exocytosis | The endocytosis process, but reverse, when cell "throw away" this large particles |
