the process by which cells use oxygen gas to break down carbohydrates, releasing chemical energy that the cell can use

autotroph

organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer

heterotroph

C6H12O6

the chemical formula for glucose

stomata

the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move

chloroplast

organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy

chlorophyll

green pigment in plants that absorbs light energy used to carry out photosynthesis

mitochondria

the cells powerhouse, turning food into energy; the organelle where cellular respiration takes place.

pigment

a colored chemical compound that absorbs light

fermentation
