| 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 space |
| 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 | a plastid that contains chlorophyll and in which photosynthesis takes place. |
| light dependent reaction | photosynthesis that require light energy that is captured by light-absorbing pigments |
| light independent reaction | reactions that convert carbon dioxide and other compounds into glucose |
| energy pyramid | 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 | 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 rich molecules for the cell |
| autotrophs | An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy. Green plants, algae, and certain bacteria |
| consumers | 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. Supplement |
| herbivores | any organism that eats only plants |
| omnivores | kind of animal that eats either other animals or plants |
| carnivores | any animal or plant that requires a staple diet consisting mainly or exclusively of animal tissue through predation or scavenging |
| decomposers | organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition. |
| spongy layer | 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 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 |
| oxygen | A colorless, tasteless, oderless, gaseous element that abounds in the atmosphere |
| carbon dioxide | is a colorless, odorless gas found in our atmosphere |
| glucose | main type of sugar in the blood and is the major source of energy for the body's cells |
| product | a chemical substance formed as a result of a chemical reaction; |
