plant processes

SOL 7.5

TermDefinition
Photosynthesis the process through which plants use water and carbon dioxide to create their food, grow and release excess oxygen into the air.
Respiration a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances
stomata/stoma Tiny openings called stomata 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 chloroplast
chloroplast (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
light dependent reaction use light energy to make two molecules needed for the next stage of photosynthesis
light independent reaction dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose.
energy pyramid graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain.
producer An autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis (using light energy)
mitochondrion 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 An organism that generally obtains food by feeding on other organisms or organic matter due to lack of the ability to manufacture own food
Herbivore A herbivore is often defined as any organism that eats only plants
omnivores An omnivore is a kind of animal that eats either other animals or plants.
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 layer of loosely packed and irregularly shaped chlorophyll-bearing cells that fills the part of a leaf
palisade layer a layer of parallel elongated cells below the epidermis of a leaf.
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. It is naturally present in air and is absorbed by plants in photosynthesis.
glucose a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates.
products a cellular product is something "manufactured" by an organelle (such as the Golgi apparatus)
