Photosynthesis
Endothermic reaction that takes place in green plants and is the method plants use to make their own food
Glucose
A simple sugar with the chemical formula C6H12O6. A product in photosynthesis and a reactant in respiration
Chlorophyll
The green chemical found in the chloroplasts of green plants that traps the Sun's energy for photosynthesis
Stomata
Microscopic holes in the leaves of plants where gases such as oxygen, carbon dioxide and water vapour can enter or exit the plant
Chloroplast
Organelle in a plant cell that contains chlorophyll; where photosynthesis takes place (contains enzymes)
Enzyme
A chemical that helps a chemical reaction but is not used up in the reaction
Respiration
A series of chemical reactions that releases energy from glucose (exothermic)
Aerobic respiration
Respiration that uses oxygen as a reactant to convert glucose into energy
Anaerobic respiration
Respiration that does not require oxygen to convert glucose into energy
Mitochondria
Organelles in plant and animal cells where respiration takes place
carbon sink
a term used to describe materials that store carbon in their structures; plants and animals can be thought of as carbon sinks
