| Term | Definition |
|---|
| Active Transport | Process by which cells transport materials against the concentration gradient using ATP energy |
| Endocytosis | Active transport process where a cell engulfs materials with a portion of the cell's plasma membrane and releases the contents inside of the cell. |
| Exocytosis | Active transport process by which materials are secreted or expelled from a cell. |
| Facilitated Diffusion | Passive transport of materials across a plasma membrane by transport proteins embedded in the plasma membrane |
| Hypertonic Solution | Solution in which the concentration of dissolved substances outside the cell is higher than the concentration inside the cell (cell shrinks) |
| Hypotonic Solution | Solution in which the concentration of dissolved substances is lower in the solution outside the cell than the concentration inside the cell. (cell bursts) |
| Isotonic Solution | Solution in which the concentration of dissolved substances in the solution is the same as the concentration of dissolved substances inside a cell. |
| Osmosis | Movement of water from an area of high concentration to low concentration |
| Passive Transport | Movement of particles across cell membranes by diffusion or osmosis; the cell uses no energy to move particles across the membrane. |
| Anaphase | During the third stage of mitosis, the sister chromatids are pulled apart and taken to opposite ends of the cell |
| Cell Cycle | Continous sequence of growth (interphase) and division (mitosis) in the cell. |
| Centriole | Barrell-like structures that produce spindle fibers and move to opposite ends of the cell during mitosis |
| Centromere | Cell structure that joins two sister chromatids of a chromosome. |
| Chromatin | Long strands of DNA found in the eukaryotic cell nucleus (condense to form chromosomes) |
| Chromosome | Cell structures that carry the genetic material that is copied and passed from generation to generation of cells. |
| Cytokinesis | Final stage of mitosis in which the cell divides to form to daughter cells |
| Interphase | Cell growth phase where a cell increases in size, carries on metabolism, and duplicates chromosomes prior to division. |
| Metaphase | In the second stage of Mitosis, the sister chromatids line up in the center of the cell |
| Mitosis | Period of nuclear cell division in which two daughter cells are formed, each containing a complete set of chromosomes |
| Organ | Group of tissues working together to perform a function |
| Organ System | Group of organs working together to perform a function |
| Prophase | First and longest phase of mitosis where chromatin coils into visible chromosomes |
| Sister Chromatids | Identical halves of a duplicated parent chromosome formed during the prophase stage of mitosis (the halves are held together by a centromere |
| Spindle | Cell structures composed of microtubule fibers; forms between the centrioles during prophase adn shorten during anaphase, pulling apart sister chromatids. |
| Telophase | Phase of mitosis during which new cells prepare for their own independent existence. |
| Tissue | Group of cells working together to perform a function |
| Cancer | Uncontrolled cell division that may be caused by environmental factors or by genetic influence. |
| Gene | Segment of DNA that codes for a particular protein |
| active_transport | transport of a substance (as a protein or drug) across a cell membrane against the concentration gradient |
