plant processes

| Term | Definition |
|---|---|
| photosynthesis | the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. |
| 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 | 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 intercellular 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 |
| chloroplasts | a plastid that contains chlorophyll and in which photosynthesis takes place (plants kitchen) |
| light dependent reaction | use light energy to make two molecules needed for the next stage of photosynthesis |
| light independent reaction | 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 | 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. |
| autotrophs | an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. |
| consumers | 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; |
| 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 feed 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 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 |
| glucose | a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates |
| products | cellular product is something "manufactured" by an organelle (such as the Golgi apparatus) |
