Plant Processes

SOL 7.5

Term	Definition
Photosynthesis	the process by which green plants and certain other organisms transform light energy into chemical energy.
Respiration	The sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells.
Stomota	Tiny openings that allow plants to exchange gases necessary for cellular processes, such as photosynthesis.
Guard cells	One of the paired cells in the epidermis of a plant that control the opening and closing of a stoma of a leaf.
Chlorophyll	The green pigment found in the chloroplasts of higher plants and in cells.
Chloroplast	the combination of two biological terms, plastid and chloros, which means green.
Light dependent reaction	The series of biochemical reactions in photosynthesis that require light energy.
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	a graphical model of energy flow in a community.
Producer	An autotrophic organism capable of producing complex organic compounds.
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.
Autotruphs	An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy.
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.
Herbivore	Any organism that eats only plants.
Omnivores	Animals that feed both on animals and plants.
Heterotrophs	An organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances, usually plant or animal matter
Carnivores	An animal or plant that requires a staple diet consisting mainly or exclusively of animal tissue through predation or scavenging.
Decoposers	organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition
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 columnar cells rich in chloroplasts found beneath the upper epidermis of foliage leaves.
Raw materials	materials or substances used in the primary production or manufacturing of goods. Raw materials are often referred to as commodities, which are bought and sold on commodities exchanges worldwide.
oxygen	A colorless, tasteless, oderless, gaseous element that abounds in the atmosphere. Supplement. In chemistry, oxygen is an element with an atomic weight of 15.96.
carbon dioxide	colorless, odorless gas found in our atmosphere. Its chemical formula is CO2, which means it is one carbon atom bonded to two oxygen atoms.
Glucose	the main type of sugar in the blood and is the major source of energy for the body's cells
products	composed of sugars, proteins, or nucleic acids, or a combination of these substances.
