| Question | Answer |
|---|---|
| Eukaryotes | Cells that contain nuclei |
| Prokaryotes | Cells that do not contain nuclei |
| Cytoplasm | Portion of the cell outside the nucleus |
| Cell Division | The process by which a cell divides int two new daughter cells |
| Mitosis | The part of eukaryotic cell division during which the cell nucleus divides |
| Cytokinesis | Division of the cytoplasm |
| Chromatids | One of two identical "sister" parts of duplicated chromosome |
| Centromere | Where the chromatids of a chromosomes are attached |
| Cell Cycle | The series of events that cells go through as they grow and divide |
| Interphase | The "in-between" period of growth in the cell cycle |
| Prophase | The chromosomes become visable and the centriols separate and take up positions on the opposite sides of the nucleus |
| Metaphase | The cromesomes line up across the center cell |
| Anaphase | The centromeres that join the sister chromatids split, allowing the sister chromatids to separate and become individual chromesomes |
| Telophase | Chromosomes begin to disperse into a tangle of dense material |
| Cytokinesis | Division of the cytoplasm |
| Cancer | A disorder in which some of the body's own cells lose the dability to control growth |
| Cohesion | An attracion between the molecules of the same substance |
| Adhesion | An attraction between molecules of different substances |
| Mixture | Material composed of two or more elements or compounds that are physically combined |
| Solution | A mixture were all the substances are evenly distributed thoughout |
| Solute | Substance that is dissolved |
| Solvent | Substance that does the dissolving |
| Suspension | Mixture of water and a non dissolved material (sand water) |
| pH scale | Indicate the conventration of H+ ions in a solution |
| Acid | Any compound that forms H+ ions in a solution |
| Base | A compound that produces hydroxide ions (-OH) |
| Bufffer | Weak acids and bases that cause sudden changes in pH |
| Monomer | Small unit that forms polymers |
| Carbohydrates | Compounds made up of carbon, hydrogen, and oxygen(main sorce of energy for living orgonisums) |
| Monosaccharides | Single sugar molecules |
| Lipids | Made up of carbon and hydrogen (used to store energy) |
| Nucleic acid | macromolecules containing hydrogen, oxegen, nitrogen, carbon, and phosphorus (stores and transmit hereditary info) |
| Proteins | Macromolecules that contain nitrogen, carbon, hydrogen, and oxygen |
| Chemical Reaction | A process that changes one set of chemicals into another |
| Reactans | The element or compound that enters a chemical reaction |
| Products | The element or compound produced by a chemical reaction |
| Activation Energy | Energy needed to start a reaction |
| Catalyst | Substance that speeds up the rate of a chemical reaction |
| Enzymes | A biological catalyst |
| Homologous | 2 sets of chromesomes come from the parents |
| Diploid | A cell that contains both sets of homologous chromosomes |
| Haploid | A cell that contains one set of chromesomes |
