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;
