Term | Definition |
---|---|
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. |
stomta | an artificial opening made into a hollow organ, especially one on the surface of the body leading to the gut or trachea. |
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 independent react | they are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the membranes of the thylakoids. |
light independent react | they are chemical reactions that convert carbon dioxide and other compounds into glucose. ... These reactions take the products of light-dependent reactions and perform additional chemical processes on them. |
energy pyramid | It is a graphic model of the energy flow in a community. The different levels represent different groups of organisms that could compose a food chain. From the bottom up, are the following: Producers: bring energy from non-living sources to the community. |
producer | a person, company, or country that makes, grows, or supplies goods or commodities for sale. |
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 |
autoteuphs | an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. |
consumers | a person or thing that eats or uses something |
herbivore | an animal that feeds on plants. |
umnivores | 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. |
decumposers | an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material. a device or installation that is used to break down a chemical substance. |
spongy layers | : 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 parallel elongated cells below the epidermis of a leaf. |
raw materials | the basic material from which a product is made. |
oxyger | Kids Definition of oxygen. : a chemical element found in the air as a colorless odorless tasteless gas that is necessary for life. oxygen. |
carban dioxode | 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 | a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates. |
products | . an article or substance that is manufactured or refined for sale. "marketing products and services" 2. MATHEMATICS a quantity obtained by multiplying quantities together, or from an analogous algebraic operation. |
