ATP ATP(Adenosine triphosphate)- a high-energy molecule that stores and supplies cells with needed energy.

Chemical Bond An attraction between two atoms resulting from a distribution of their outer electrons. Covalent Bond : Sharing of one or more pairs of e-

Chemical Energy Chemical Energy - energy stored in the bonds of chemical compounds, released in a chemical reaction, often producing heat. Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy.

Chlorophyll A green pigment that absorbs light to provide energy for photosynthesis.

Chloroplast (In green plant cells) the cell part that contains chlorophyll and where photosynthesis takes place.

Light Dependent reactions the reactions that convert sunlight to ATP on the thylakoid membranes.

Light independent reactions - reactions that convert CO2 and other compounds into glucose in the stroma. stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes.

photosynthesis - using sunlight to make foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by product.
