Plant Processes
SOL 7.5
| 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 |
| Stomata | open and close to allow the intake of carbon dioxide and the release of oxygen |
| 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. |
| 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 |
| Light independent reaction | The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. |
| Energy pyramid | An energy pyramid is a graphical model of energy flow in a community. |
| Producer | Producers are organisms that make their own food |
| 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 from inorganic sources |
| Herbivore | an animal that feeds on plants |
| Omnivore | 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 or plant (particularly insect- and invertebrate-eating plants) that requires a staple diet consisting mainly or exclusively of animal tissue through predation or scavenging. |
| 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 |
| Palisades 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 |
| Glucose | a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates. |
| Products | a substance produced during a natural, chemical, or manufacturing process. |
