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. |
chlorophyll | a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. |
chloroplast | (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place. |
light dependent reaction | The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis |
light independent | he light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. |
energy pyramid | An energy pyramid is a graphical model of energy flow in a community. |
producer | include green plants, which produce food through photosynthesis, and certain bacteria that are capable of converting inorganic substances into food through chemosynthesis. |
mitochondria | 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 | is an organism that feeds on plants or other animals for energy. |
herbivores | as any organism that eats only plants. By that definition, many fungi, some bacteria, |
omnivores | An omnivore is an animal that eats both plants and animals for their main food |
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. All animals, protozoans, fungi, and most bacteria are heterotrophs. |
carnivores | A carnivore is an animal that eats a diet consisting mainly of meat, whether it comes from live animals or dead ones (scavenging). ... |
decomposers | Decomposers are 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 parallel elongated cells below the epidermis of a leaf. |
raw materials | t he 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. |
products | is a substance that is formed as the result of a chemical reaction. ... |
