Cells and Cell Tran.
Cells and Cellular Transport
| Question | Answer |
|---|---|
| The process by which cells use energy to transport molecules throught the cell membrane from high concentration to low concentration | Active Transport |
| A compound that stores and is used as energy in cells. | ATP (adenine triphosphate) |
| The basic unit of structure and function that makes up all organisms. | Cell |
| The thin boundary between the cell and its external environment. Made of phosolipids and proteins | Cell Membrane |
| The process in which nutrients are broken down releasing the chemical energy stored in them. | Cellular Respiration |
| A green organelle in plant cells containing chlorophyll; where photosynthesis takes place. | Chloroplast |
| An organelle that transports proteins and other materials from one part of the cell to another (two types: smooth; rough). | Endoplasmic Reticulum |
| Pod-shaped organelles that contain enzymes used to extract energy from nutrients. "The powerhouse of the cell." | Mitochondria |
| A body structure made of different kinds of tissues combined to perform a specific function. | Organ |
| Several organs working together to perform a specific function. | Organ System |
| A structure within a cell that carries out a specific function. Name means "tiny organ." | Organelle |
| Made of cellulose and surrounds plant cells. Main function is to prevent loss of water but also provides structural support. | Cell Wall |
| Packages proteins for transport out of cell. typically located near the cell membrane | Golgi Body (apparatus) |
| Gel like substance inside the cell between the cell membrane and nucleus. | Cytoplasm |
| The DNA of the cell, as it appears during mitosis, in its coiled and dense form. | Chromosomes |
| The DNA of the cell as it appears during the portion of the cell cycle when the cell is carrying out its normal life functions. | Chromatin |
| The idea that all living things are basic structure of form and function are cells, cells only arise from other cells | Cell Theory |
| Cells develop in different ways to perform different functions. | Cell Specialization |
| One of two structures found only in animal cells. Play important role in mitosis making the spindle fibers. | Centriole |
| Membrane surrounding the nucleus of plant and animal cells. | Nuclear Envelope. |
| "The brain of the cell." Contains the genetic information of the cell. | Nucleus |
| Site of ribosome production inside the nucleus. | Nucleolus |
| Name means "storage sac." Rarely found in animal cells, large in plant cells and store food, water and wastes. | Vacuole |
| Tiny two part structure in the cytoplasm that is envolved in protein synthesis in association with the rough ER. | Ribosomes |
| Protein filament network that helps a cell maintain its shape. | Cytoskeleton |
| The mass of a given substance being dissolved (solute) in a given volume of a solvent (the substance doing the dissolving). | Concentration |
| The movement of a substance from high concentration to low concentration. | Diffusion |
| The diffusion of water. | Osmosis |
| The transport of lager molecules through protein channels in the cell membrane. | Facillitated Diffusion |
| The concentration of solutes is the same inside and outside the cell. Equilibrium. | Isotonic |
| Solution outside the cell has a higher concentratiion than inside the cell. Water is lost. | Hypertonic |
| Solution outside the cell has a lower concentration than inside the cell. Water gain. | Hypotonic |
