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. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. |
| respiration | the action of breathing. |
| stomata | a small mouth-like opening in some lower animals. |
| 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 | (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place. |
| light dependent reaction | Taking in oxygen is very important because it allows your cells to do things, like make energy from the food you eat. Plants 'breathe' too, but they do it through tiny openings in leaves called stomata (singular: stoma). |
| light independent reaction | is a tiny opening or pore that is used for gas exchange. They are mostly found on the under-surface of plant leaves. ... Air enters the plant through these openings. |
| energy pyramid | is a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain. From the bottom-up. |
| 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 (cristae). |
| autotrophs | an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. |
| consumers | a person who purchases goods and services for personal use. |
| herbivore | an animal that feeds on plants. |
| omnivore s | 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. |
| decomposers | 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 layer | like a sponge, especially in being porous, compressible, elastic, or absorbent. |
| 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 (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. a syrup containing glucose and other sugars, made by hydrolysis of starch and used in the food industry. |
| products | an article or substance that is manufactured or refined for sale. |
