Term | Definition |
---|---|
photosynthesis | : the process by which a green plant turns water and carbon dioxide into food when the plant is exposed to light |
respiration | : the act or process of breathing |
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. |
gaurd cells | either of two specialized epidermal cells that flank the pore of a stoma and usually cause it to open and close. |
chlorophyll | the green substance in plants that makes it possible for them to make food from carbon dioxide and water |
chloroplast | a plastid that contains chlorophyll and in which photosynthesis takes place |
light dependent reaction | he series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy |
light independent react | he series of biochemical reactions in photosynthesis that do not require light to proceed, and ultimately produce organic molecules from carbon dioxide. |
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. From the bottom-up, they are as follows: Producers — bringing energy |
producer | a person who produces |
mitochondria | an organelle in the cytoplasm of cells that functions in energy production. |
autotrophs | any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists. |
consumers | a person or thing that consumes. |
herbivore | a herbivorous animal. |
omnivores | someone or something that is omnivorous. |
heterotrophs | an organism requiring organic compounds for its principal source of food. |
carnivores | an animal that eats flesh. |
decomposers | a person or thing that decomposes. |
spongy layers | 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 meterials | the 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 | an article or substance that is manufactured or refined for sale. |
