Terms | Definitions |
|---|---|
 Diffusion | The movement of particles from an area of high concentration to an area of low concentration. |
| Osmosis | The diffusion of WATER through a semipermeable membrane. |
| Passive Transport | The movement of substances across a cell membrane without the use of energy by the cell. |
| Active Transport | The movement of substances across the cell membrane that requires the cell to use energy. |
| Endocytosis | The process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell. |
| Exocytosis | The process by which a cell releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane. |
| Cell Cycle | The life cycle of a cell. |
| Chromosome | In a eukaryotic cell, one of the stuctures in the nucleus that are made of DNA. In a prokaryotic cell, the main ring of DNA. |
| Homologous chromosomes | Chromosomes that have the same sequence of genes and the same structure. |
| Mitosis | In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes. |
| Interphase | Cells grow to adult size and makes copy of DNA and prepares to divide. |
| Mitosis (Prophase) | Chromatin material condenses, spindle fibers form, nuclear membrane dissolves. |
| Mitosis (Metaphase) | Chromosomes line up at cell center, attach to spindle fibers. |
| Mitosis (Anaphase) | Centromeres split chromatids, move to opposite ends of cell, cytoplasm starts division. |
| Mitosis (Telophase) | Chromosomes stretch out, new nuclear membrane forms. |
| Cytokinesis | Two daughter cells are formed. |
| PMAT | Prophase, Metaphase, Anaphase, Telophase. |
