Term | Definition |
---|---|
Photosynthesis | he process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. |
Respiration | process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide |
Stomata | many 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 series of biochemical reactions in photosynthesis that require light energy |
Light independent reaction | are chemical reactions that convert carbon dioxide and other compounds into glucose. |
Energy pyramid | is a graphical model of energy flow in a community. |
Producer | a person, company, or country that makes, grows, or supplies goods or commodities for sale. "an oil producer" |
Mitochondrion | an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. |
Autotrophs | an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. |
Consumers | a person or thing that eats or uses something |
Herbivore | an animal that feeds on plants |
Omnivores | an animal or person that eats food of both plant and animal origin. |
Hetetrotrophs | n organism deriving its nutritional requirements from complex organic substances. |
Carnivores | an animal that feeds on flesh. |
Decomposers | an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material. |
Spongy Layer | 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 made. |
Oxygen | colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air. Oxygen forms about 20 percent of the earth's atmosphere |
Carbon Dioxide | a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. |
Glucose | a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates. |
Products | a substance produced during a natural, chemical, or manufacturing process |
