Plant Processes
SOL 7.5
| Term | Definition |
|---|---|
| Photosynthesis | the process by which green plants and certain other organisms transform light energy into chemical energy. |
| Respiration | The sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells. |
| Stomota | Tiny openings that 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 chloroplasts of higher plants and in cells. |
| Chloroplast | the combination of two biological terms, plastid and chloros, which means green. |
| Light dependent reaction | The series of biochemical reactions in photosynthesis that require light energy. |
| Light independent reaction | The series of biochemical reactions in photosynthesis that do not require light to proceed, and ultimately produce organic molecules from carbon dioxide. |
| Energy pyramid | a graphical model of energy flow in a community. |
| Producer | An autotrophic organism capable of producing complex organic compounds. |
| Mitochondrion | A spherical or rod-shaped organelle with its own genome, and is responsible for the generation of most of the cell's supply of adenosine triphosphate through the process of cellular respiration. |
| Autotruphs | An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy. |
| 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; a heterotroph. |
| Herbivore | Any organism that eats only plants. |
| Omnivores | Animals that feed both on animals and plants. |
| Heterotrophs | An organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances, usually plant or animal matter |
| Carnivores | An animal or plant that requires a staple diet consisting mainly or exclusively of animal tissue through predation or scavenging. |
| Decoposers | organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition |
| Spongy layer | a layer of loosely packed and irregularly shaped chlorophyll-bearing cells that fills the part of a leaf between the palisade layer and the lower epidermis -- called also spongy parenchyma, spongy tissue. |
| Palisade layer | a layer of columnar cells rich in chloroplasts found beneath the upper epidermis of foliage leaves. |
| Raw materials | materials or substances used in the primary production or manufacturing of goods. Raw materials are often referred to as commodities, which are bought and sold on commodities exchanges worldwide. |
| oxygen | A colorless, tasteless, oderless, gaseous element that abounds in the atmosphere. Supplement. In chemistry, oxygen is an element with an atomic weight of 15.96. |
| carbon dioxide | colorless, odorless gas found in our atmosphere. Its chemical formula is CO2, which means it is one carbon atom bonded to two oxygen atoms. |
| Glucose | the main type of sugar in the blood and is the major source of energy for the body's cells |
| products | composed of sugars, proteins, or nucleic acids, or a combination of these substances. |
