Term Definition
photosynthesis he 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 a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
chloroplast (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
chlorophyll a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.
glucose a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates.
mitochondria energy producer for a cell
photosynthesis equation 6CO2 + 6H2O —> C6H12O6 + 6O2
respiration equation C6h12o6 + 6o2 —> 6co2 + 6h2o + ATP
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 intermingling of substances by the natural movement of their particles."the rate of diffusion of a gas"
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.
active transport the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
