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, 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. |
Chlororhpyll | a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. |
Chloroplast | 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 | or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. |
Energy Pyramid | graphical representation designed to show the biomass or bio productivity |
Prouducer | Producers are organisms that make their own food; they are also known as autotrophs. |
Mitochondria | an organelle found in large numbers in most cells and respiration and energy production occur |
Autotrophs | n organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. |
Consumers | Consumers are organisms that eat organisms from a different population |
Herbevories | an animal that feeds on plants |
Omnivores | an animal or person who eats food of both plant and animal origin. (plants and meats) |
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 | 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 | most abundant, colorless, odorless reactive gas ( what we breathe). |
Carbon Dioxide | what we breathe out after we breathe in the oxygen. |
Glucose | type of sugar you get from foods you eat, and your body uses it for energy. |
Products | a chemical substance formed as a result of a chemical reaction. |
