| Question | Answer |
|---|---|
| Cell | A cell is the smallest, basic structural, functional, and biological unit of all living organisms |
| Osmosis | A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. |
| Cell Theory | a fundamental biological principle stating that all living organisms are composed of one or more cells, cells are the basic unit of structure and function in organisms, and all cells arise from pre-existing cells. |
| Cell Wall | a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose. |
| Cell Membrane | a, flexible, selectively permeable barrier surrounding all cells, separating the cytoplasm from the external environment |
| Nucleus | The central and most important part of an object, movement, or group, forming the basis for its activity and growth. |
| Organelle | Any of a number of organized or specialized structures within a living cell. |
| Ribosome | A minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins. |
| Nucleic Acid | essential macromolecules that store, transmit, and express genetic information in all living organisms and viruses |
| Selectively Permeable | a biological or synthetic barrier that allows specific molecules and ions to pass through while blocking others |
| Cytoplasm | The material or protoplasm within a living cell, excluding the nucleus. |
| Mitochondria | An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae). |
| Endoplasmic Reticulum | a crucial network of membranes in eukaryotic cells that synthesizes, folds, and transports proteins (via rough ER) and lipids (via smooth ER) |
| Golgi Apparatus | a membrane-bound eukaryotic organelle, consisting of stacked sacs called cisternae, that functions as the cell's "post office". |
| Chloroplast | (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place. |
| Lysosome | An organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane. |
| DNA | A self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. |
| Passive Transport | energy-independent movement of substances across cell membranes along a concentration gradient (high to low concentration) |
| Active Transport | the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration— |
| Diffusion | the spontaneous, passive movement of particles (atoms, ions, or molecules) from a region of higher concentration to a region of lower concentration, driven by thermal energy |
| Tissue | Any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products. |
| Organ | A part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in humans. |
| Organ system | a group of anatomically related organs that work together to perform complex, specialized functions necessary for an organism's survival, such as digestion, circulation, or respiration. |
| Endocytosis | The taking in of matter by a living cell by invagination of its membrane to form a vacuole. |
| Exocytosis | A process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane. |
