Plant Processes

SOL 7.5

TermDefinition
Photosynthesis the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Respiration Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose.
Stomata any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width that allows movement of gases in and out of the inter cellular spaces.
Guard cells each of a pair of curved cells that surround a stoma, becoming larger or smaller according to the pressure within the cells.
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.
Chloroplast a plastid that contains chlorophyll and in which photosynthesis takes place.
Light dependent reaction The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis
Light independent reaction The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose.
Energy pyramid An energy pyramid is a graphical model of energy flow in a community.
Producer Producers are organisms capable of creating simple carbohydrates such as glucose
Mitochondria an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
Autotrophs an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Consumers they consume nutrients and bacteria
Herbivore an animal that feeds on plants.
Omnivores an animal or person that eats food of both plant and animal origin.
Heterotrophs an organism deriving its nutritional requirements from complex organic substances.
Carnivores an animal that feeds on flesh.
Decomposers an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
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.
Palicade layer Palisade cells are plant cells located in leaves, right below the epidermis and cuticle
raw materials the basic material from which a product is made.
Oxygen a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air
carbon dioxide a colorless, odorless gas produced by burning carbon and organic compounds and by respiration.
Glucose a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates.
