stomata are very small openings in membranes, particularly in plants, through which water and gas pass.
guard cells is an epidermal cell that can open the stomata to take in or release oxygen, carbon dioxide and water,
cholrophyll a green pigment, present in all green plants responsible for the absorption of light to provide energy for photosynthesis.
light dependent reaction 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 in the form of ATP and NADPH.
light independent reaction 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.
producer An autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis
mitochondrion an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
autotroph an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
counsumers An organism that generally obtains food by feeding on other organisms
