plant processes
SOL 7.5
| Term | Definition |
|---|---|
| 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) |
