Diffusion | The movement of particles from regions of higher density to regions of lower density. |
Osmosis | The diffusion of water through a semipermiable membrane. |
Passive Transport | The movement of substances across the cell membrane without the use of energy by the cell.The movement of substances |
Active Transport | The movement of substances across the cell membrane that requires the cell to use energy. |
Endocytosis | The process by which the cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell. |
Exocytosis | The process in which the cell releases a particle by 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. |
Chromosomes | 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 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. |
