The Cell in Action
Daniel B.
| Question | Answer |
|---|---|
| Diffusion- | Movement from areas of high concentration (crowded) to areas of low concentration (less crowded). |
| 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 in which a cell releases a particle be enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane. |
| Photosynthesis- | The process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food. |
| Cellular Respiration- | The process by which cells use oxygen to produce energy from food. |
| Fermentation- | The breakdown of food without the use of oxygen. |
| Cell Cycle- | The life cycle of a cell. |
| Chromosome- | In a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; 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. |
| Cytokinesis- | The division of the cytoplasm of a cell. |
