TermDefinition
photosynthesis Biochemistry. 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.
stomata Botany One of the tiny openings in the epidermis of a plant, through which gases and water vapor pass. Stomata permit the absorption of carbon dioxide necessary for photosynthesis from the air, as well as the removal of excess oxygen.
guard cells botany one of a pair of crescent-shaped cells that surround a pore (stoma) in the epidermis. Changes in the turgidity of the cells cause the opening and closing of the stoma.
chlorophyll The green pigment found in the chloroplasts of higher plants and in cells of photosynthetic microorganisms (e.g. photosynthetic bacteria), which is primarily involved in absorbing light energy for photosynthesis.
chloroplast Chloroplast is the combination of two biological terms, plastid (an organelle in a plant cell), and chloros, which means green. If you're reading about plant biology, you'll probably recognize chloros in chlorophyll, which is one of the pigments important
light dependent reaction The series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy in the form of ATP and NADPH.
light independent reaction The series of biochemical reactions in photosynthesis that do not require light to proceed, and ultimately produce organic molecules from carbon dioxide.
energy pyramid Energy Pyramid Definition. ... The base of the energy pyramid indicates the energy available within primary producers. Primary producers, also known as autotrophs, are organisms which create their own food by taking their energy from non-living sources of
producer An autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis (using light energy) or through chemosynthesis (using chemical energy)
mitochondrion A spherical or rod-shaped organelle with its own genome, and is responsible for the generation of most of the cell's supply of adenosine triphosphate through the process of cellular respiration.
autotephs An autotroph is an organism that can make its own food by synthesizing organic nutrients from inorganic materials, using energy from sunlight or a chemical source to drive the process. ... Autotrophs are the primary producers in ecosystems and form the ba
consumers An organism that generally obtains food by feeding on other organisms or organic matter due to lack of the ability to manufacture own food from inorganic sources; a heterotroph. Supplement.
herbivore Herbivore. A herbivore is often defined as any organism that eats only plants. By that definition, many fungi, some bacteria, many animals, about 1% of flowering plants and some protists can be considered herbivores. ... In zoology, an herbivore is an ani
omnivores An omnivore is an organism that eats both animals and plants. An animal with such a diet is said to be "omnivorous." An omnivore that you're probably pretty familiar with are humans - most humans (other than those who don't get any nutrition from animal p
heterotrophs heterotrophs. An organism that is unable to synthesize its own organic carbon-based compounds from inorganic sources, hence, feeds on organic matter produced by, or available in, other organisms.
carnivores Carnivore. An animal or plant (particularly insect- and invertebrate-eating plants) that requires a staple diet consisting mainly or exclusively of animal tissue through predation or scavenging.
decomposers Decomposers are organisms that break down dead or decaying organisms and wastes. Their role is ecologically essential as they recycle the nutrients through a natural biological process (decomposition). Examples of decomposers are fungi and bacteria that o
spongy layer spongy parenchyma. A layer of cells in the interior of leaves, consisting of loosely arranged, irregularly shaped cells that have chloroplasts. The spongy parenchyma has many spaces between cells to facilitate the circulation of air and the exchange of ga
palisade layer palisade layer. A layer of cells just below the upper surface of most leaves, consisting of cylindrical cells that contain many chloroplasts and stand at right angles to the leaf surface.
raw materials A bio-based material is a material intentionally made from substances derived from living (or once-living) organisms. ... Strictly the definition could include many common materials such as wood and leather, but it typically refers to modern materials tha
oxygen In chemistry, oxygen is an element with an atomic weight of 15.96. ... In biology, the oxygen plays a crucial role in various biochemical and physiological processes, such as in cellular respiration.
carbon dioxide In animals, carbon dioxide is a chemical compound that accumulates in the tissues and removed from the body when an animal exhales. It is therefore a metabolic byproduct of carbohydrate metabolism. In plants, carbon dioxide is an important reactant to pro
glucose Glucose is a simple sugar used by the body to make ATP, which is used by the body for energy. The body converts carbohydrates in food into simple sugars in the digestive system; the glucose enters the bloodstream, causing its level to rise and triggering
