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 | 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 substance |
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. 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 | Light-dependent reaction. From Biology-Online Dictionary | Biology-Online Dictionary. Definition. The series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments (such as chlorophyll) to be conv |

Energy pyramid | The different levels represent different groups of organisms that might compose a food chain. From the bottom-up, they are as follows: Producers — bring energy from nonliving sources into the community. |
Producer | An autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis (using light energy) or through chemosynthesis (using chemical energy) Supplement. Producers are in the first tro |
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. |
