| 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. |
| stoma | an artificial opening made into a hollow organ, especially one on the surface of the body leading to the gut or trachea. |
| 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 react | The 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. The different levels represent different groups of organisms that might compose a food chain. |
| producer | An autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis |
| mitochondrion | Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy |
| autotrouphs | an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. |
| 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 |
| herbivore | A herbivore is often defined as any organism that eats only plants. |
| omnivores | 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 | 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 |
| palisade layer | a layer of parallel elongated cells below the epidermis of a leaf. |
| raw materials | the basic material from which a product is mad |
| 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 |
| glucose | a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates |
