TermDefinition
Photosynthesis the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.
Respiration the sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off.
stoma Also stomate. Botany . any of various small apertures, especially one of the minute orifices or slits in the epidermis of leaves, stems, etc., through which gases are exchanged.
Guard cells either of two specialized epidermal cells that flank the pore of a stoma and usually cause it to open and close.
Chloroplast a plastid containing chlorophyll. where pohtosynthesis occurs
Light dependent reaction The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes
Light independent react The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid me
Energy pyramid An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain. From the bottom-up, they are as follows: Producers — bring energy from nonliving sources in
Producer An autotrophic organism that serves as a source of food for other organisms in a food chain. Producers include green plants, which produce food through photosynthesis, and certain bacteria that are capable of converting inorganic substances into food thro
Mitochodrion an organelle in the cytoplasm of cells that functions in energy production
Autotrophs any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists.
Consumers Ecology . an organism, usually an animal, that feeds on plants or other animals.
Herbivore an animal that feeds on plants.
Omnivores an animal or person that eats food of both plant and animal origin.
Heterotrophs biology . an organism requiring organic compounds for its principal source of food.
Carnivores a flesh-eating mammal of the order Carnivora, comprising the dogs, cats, bears, seals, and weasels.
Decomposers Ecology . an organism, usually a bacterium or fungus, that breaks down the cells of dead plants and animals into simpler substances.
Spongy layer : a layer of loosely packed and irregularly shaped chlorophyll-bearing cells that fills the part of a leaf between the palisade layer and the lower epidermis -- called also spongy parenchyma, spongy tissue.
Palisade layer a layer of parallel elongated cells below the epidermis of a leaf.
Raw materials basic material from which a product is made.
Oxygen a colorless, odorless, gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature. It is the supporter of combustion in air and was the standard of atomic, combining, and molecular weights until
Carbon dioxide a colorless, odorless, incombustible gas, CO2, present in the atmosphere and formed during respiration, usually obtained from coal, coke, or natural gas by combustion, from carbohydrates by fermentation, by reaction of acid with limestone or other carbona
Glucose Also called starch syrup. a syrup containing dextrose, maltose, and dextrine, obtained by the incomplete hydrolysis of starch.
Products quantity obtained by multiplying quantities together, or from an analogous algebraic operation
