Biology
| Term | Definition |
|---|---|
| Cell theory | cell theory is a scientific theory which describes the properties of cells |
| cytoplasm | the material or protoplasm within a living cell, excluding the nucleus |
| organelle | any of a number of organized or specialized structures within a living cell. |
| prokaryotic cell | y of the typically unicellular microorganisms that lack a distinct nucleus and membrane-bound organelles and that are classified as a kingdom |
| eukaryotic cell | An organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins (histones) into chromosomes. |
| nucleus | in physical science, an atom's central region, which is made up of protons and neutrons |
| endoplasmic reticulum | a system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipid |
| ribosome | a cell organelle composed of RNA and protein; the site of protein synthesis |
| golgi apparatus | a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport |
| vesicle | a small cavity or sac that contains materials in a eukaryotic cell; forms when part of the cell membrane surrounds the materials to be taken into the cell or transported within the cell |
| mitochondrion | in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP |
| vacuole | a fluid-filled vesicle found in the cytoplasm of plant cells or protozoans |
| lysosome | a cell organelle that contains digestive enzymes |
| centriole | an organelle that is active during mitosis |
| cell wall | a rigid structure that surrounds the cell membrane and provides support to the cel |
| chloroplast | an organelle found in plant and algae cells where photosynthesis occurs |
| cell membrane | a phospholipid layer that covers a cell’s surface and acts as a barrier between the inside of a cell and the cell’s environment |
| phospholipid | a lipid that contains phosphorus and that is a structural component in cell membranes |
| fluid mosaic model | |
| selective permeability | |
| recepter | a specialized sensory nerve that responds to specific types of stimuli |
| passive transport | the movement of substances across a cell membrane without the use of energy by the cel |
| diffusion | the movement of particles from regions of higher density to regions of lower density |
| concentration gradient | a difference in the concentration of a substance across a distance |
| osmosis | the diffusion of water or another solvent from a more dilute solution (of a solute) to a more concentrated solution (of the solute) through a membrane that is permeable to the solvent |
| isotonic | |
| hypertonic | |
| hypotonic | |
| facilitated diffusion | |
| active transport | |
| endocytosis | |
| phagocytosis | |
| exocytosis |
