Term Definition
Photosynthesis A process by which plants convert sunlight, water, and carbon dioxide into food energy, oxygen, and water.
Cellular Respiration The process by which the chemical energy of "food" molecules is released and changed into ATP.
Chloroplast An elongated cell organelle containing chlorophyll where photosynthesis takes place.
Chlorophyll A green molecule which uses light energy from sunlight to change water and carbon dioxide gas into sugar and oxygen.
Glucose Simple sugar that is an important energy source in living organisms and is a component of many carbohydrates.
Mitochondria Rod-shaped organelles with a double membrane which converts the energy stored in glucose into ATP for the cell.
Photosynthesis equation Water + Carbon dioxide + sun to oxygen+ glucose (sugar)
Respiration Equation Oxygen + glucose(sugar)to water + carbon dioxide + energy
Carbon Dioxide a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.
Diffusion The movement of molecules from an area that is highly concentrated to an area in which they are less concentrated.
Osmosis The diffusion of water across a selectively permeable membrane.
Active Transport the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
