| Biology word | definition | Alternate words |
|---|---|---|
| Plasma membrane | The semipermeable membrane that encloses the cytoplasm of a cell | plastic, plaster, member, dismember |
| Dynamic equilibrium | a state of balance achieved by two forces in motion; also, a state of apparent repose between two reactions going in opposite directions at equal speed | dynasty, equal, equality, equation |
| Diffusion | Also called migration. an intermingling of molecules, ions, etc., resulting from random thermal agitation, as in the dispersion of a vapor in air. | differ, difference, diffuse, edify |
| Hypertonic Solution | any solution with a higher salt concentration than normal body cells so that the water is drawn out of the cells by osmosis; any solution with a higher osmotic pressure than another solution | hyperbole, hyperbaton, hyperglycemia, hyperspace |
| Hypotonic solution | any solution with a lower salt concentration than normal body cells so that water flows into the cells by osmosis; any solution with a lower osmotic pressure than another solution | hypothalamus, hypotenuse, hypothesis, hypochondria |
| isotonic solution | a solution having the same osmotic pressure as blood | isosceles, isotope, isometric, isobar |
| osmosis | the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane | endocrine, endorphin, endomorph, hypothesis |
| passive transport | The movement of a chemical substance across a cell membrane without expenditure of energy by the cell, as in diffusion. | transliterate, transmit, transparent, transfix |
| chromosome | any of several threadlike bodies, consisting of chromatin, that carry the genes in a linear order: the human species has 23 pairs, designated 1 to 22 in order of decreasing size and X and Y for the female and male sex chromosomes respectively. | chrome, chromatic, monochrome, chromatin |
| cytokinesis | the division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus. | cytoplasm, telekinesis, pyrokinesis, hide |
| mitosis | the usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being | mitochondria, miter, samite |
| cancer | a malignant and invasive growth or tumor, esp. one originating in epithelium, tending to recur after excision and to metastasize to other sites | carcinoma, cancerous |
| adenosine triphosphate | a nucleotide derived from adenosine that occurs in muscle tissue; the major source of energy for cellular reactions | triad, trey, three, triangle |
| photosynthesis | the synthesis of complex organic materials, esp. carbohydrates, from carbon dioxide, water, and inorganic salts, using sunlight as the source of energy and with the aid of chlorophyll and associated pigments | photograph, photography, synthesize, synthetic |
| aerobic respiration | a type of respiration in which oxygen is taken in and carbon dioxide and water are produced; also, the use of oxygen in the breakdown of foodstuffs to create energy | air, life, resipire, aerobics |
| anaerobic respiration | in biology, a form of incomplete intracellular breakdown of sugar or other organic compounds in the absence of oxygen that releases energy; cellular respiration in the absence of oxygen | anagram, analects, analgesic, analysis |
| glycolysis | the catabolism of carbohydrates, as glucose and glycogen, by enzymes, with the release of energy and the production of lactic or pyruvic acid. | catalyst, electrolysis, hydrolysis, analysis |
| fermentation | The anaerobic conversion of sugar to carbon dioxide and alcohol by yeast | ferment, fervor, fervent, fervid |
