plant process

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. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
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 plural form of stoma.
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 (in green plant cells) 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: the energy storage molecule ATP and the reduced electron carrier NADPH.
light independet react The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light,.
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.
producer Producers are organisms that make their own food; they are also known as autotrophs.
mitochondrion an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers
autotrophs an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
consumers is an organism that feeds on plants or other animals for energy
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.
palisade 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.
raw materials the basic material from which a product is made.
oxygen Oxygen is used by animals and plants in the respiration (breathing) process.
carban dioxide a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.
glucose Having too much sugar in the blood
products In chemistry, a product is a substance that is formed as the result of a chemical reaction.
