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 | 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 | an artificial opening made into a hollow organ, especially one on the surface of the body leading to the gut or trachea. |
| guard cells | ach of a pair of curved cells that surround a stoma, becoming larger or smaller according to the pressure within the cells. |
| chlorophyll | green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. |
| chloroplast | n green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place |
| light dependent reaction | The series of biochemical reactions in photosynthesis that require light energy that is captured by light |
| light independent reaction | dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds |
| energy pyramid | a graphical model of energy flow in a community. |
| producer | n autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis |
| mitchondrion | 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 | n 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. |
| omnivore | An omnivore is a kind of animal that eats either other animals or plants. |
| heterotrophs | An organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances |
| carnivores | An animal or plant (particularly insect- and invertebrate-eating plants) |
| decomposers | organisms that break down dead or decaying organisms, |
| spongy layer | layer of loosely packed and irregularly shaped chlorophyll-bearing cells that fills the part of a leaf between the palisade layer |
| palisade layer | layer of columnar cells rich in chloroplasts found beneath the upper epidermis |
| raw materials | materials or substances used in the primary production |
| oxygen | an element with an atomic weight of 15.96. |
| carbon dioxide | colorless, odorless gas found in our atmosphere. Its chemical formula is CO2, |
| glucose | main type of sugar in the blood and is the major source of energy for the body's cells. |
| products | chemical substance formed as a result of a chemical reaction; |
