| Question | Answer |
|---|---|
| Abiotic | non-living elements of the enviroment, ex. water, rocks, sunlight, air etc |
| Biotic | living things of the enviroment, ex. people, plants, bacteria etc |
| Organic | molecules containing large amounts of carbon |
| Carbohydrate | main source of energy |
| Lipids | energy storage |
| Proteins | controls cell functions |
| Nucleic Acids | store and transmit genetic info |
| Chemical Reaction | a process that changes one set of chemicals into another |
| Activation | the energy required to start a chemical reaction |
| Reactants | chemicals that enter a reaction |
| Products | chemicals that are produced by a reaction |
| Enzymes | increase rate of a chemical by lowering the activation energy |
| Cell | the most basic unit of life |
| Prokaryotes | the least complex cell that contains no nucleus |
| Eukaryotes | the most complex cell that contains a nucleus |
| Nucleus | membrane- bound organelle that contains genetic info |
| Photosynthesis | uses CO2, light, and water to produce glucose and oxygen |
| Mitochondria | uses oxygen & glucose to produce CO2 & ATP |
| Sterioscope | used for low magnification, primarily for disection and identification of organisms |
| Compound Microscope | used for greater magnification |
| Field of View | what you see when looking into the microscope |
| Magnification | total magnification=eyepiece x objective |
| Cell Transport | how cells move materials in and out across the cell |
| Plasma Membrane | semi-permiable barrier that regulates passage of materials |
| Passive Transport | the movement of materials without using energy (ATP) |
| Diffusion | the slow movement of small particles and gasses through the plasma membrane |
| Equilibrium | equal concentration |
| Facilitated Diffusion | proteins in the plasma membrane allow larger molecules to diffuse into and out of the cell |
| Osmosis | the facilitated diffusion of water |
| Homeostasis | a cells attempt to maintain a near constant condition |
| Adenosine Triphosphate (ATP) | stores energy and releases energy |
| Adenosine Diphosphate (ADP) | stores energy by adding a phosphate to create ATP |
| Releasing Energy | A bond is broken between the last two phosphates in ATP to release energy and create ADP |
| Autotroph | organisms that make their own food; plants and some protists |
| Heterotroph | organisms that obtain food by consuming other organisms |
| Deoxyribose Nucleic Acid (DNA) | stores, copies, and transmits genetic info |
| Nucleotide | made up of a phosphate group, a sugar, and a nitrogenous base |
| 4 Types of Bases | 1. Adenine (A) 2. Guanine (G) 3. Cytosine (C) 4. Thynine (T) (can be strung together in many different ways) |
