Photosynthesis


 * Photosynthesis**

Photosynthesis is the use of sunlight to convert water (H20) and carbon dioxide (CO2) into carbohydrates, sugar, starch, and oxygen (which is the waste product) Click here!
 * Jan van Helmont*** (1643)-Trees gain most of there mass from water.

 * Joseph Priestley*** (1771)-using a jar, candle, and a plant priestley discovered plants realease a substance (now known as Oxygen) to keep the candle from blowing out.


 * Jan Ingenhousz*** (1779)- concludes that plants need sunlight to produce oxygen.

The over all equation equation for photosynthesis can be shown as followed...
 * ~Photosynthesis (Equation)~***

***6 CO2 + 12 H2O → C6H12O6 + 6H2O*** Carbon dioxide + Water → sugar + oxygen

*In addition to water and carbon, photosynthesis requires light and chlorophyll (found in cloroplast)

*The plants main light absoabing*


 * ~*Photsynthesis (chloroplast)*~***

Chloroplast is were photosynthesis takes place.
