Term | Definition |

Active Transport | the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy. |
Consumer | a person who purchases goods and services for personal use. |
Diffusion | the spreading of something more widely. |
Endocytosis | the taking in of matter by a living cell by invagination of its membrane to form a vacuole. |
Equilibrium | a state in which opposing forces or influences are balanced. |
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. |
Fermentation | the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat. |
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. |
Producer | a person, company, or country that makes, grows, or supplies goods or commodities for sale. |
Passive Transport | Passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. |
Photosynthesis | the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. |
cellular respiration | Cellular respiration is what cells do to break up sugars into a form that the cell can use as energy. This happens in all forms of life. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. |
