History
For this project Will Just DO-ing It Help it helps to know about the history of plants and what plants do to survive so here it is. The 3 basics of photosynthesis is light, water, and oxygen each if these things were stumbled upon by different people. For water it was discovered by a man by the name of Jan Baptista Van Helmont in 1649 he stumbled upon this by doing a experiment on soil. His experiment was based on if he transplanted a young willow tree into a large container of soil if the willow tree formed its tissues around the soil then the soil should weigh less because of the tree absorbing nutrients he made sure nothing interfered with his experiment. Ovbvuiosly watering it ocassionly

He Found this out by following on to Joseph Pristleys theory and procedure he put a small plant in a small transparent box with a lit candle then exposed the box to direct sunlight and waited a few days and when he came back and saw that the candle was still lit. Then he tried the experiment again but now in the dark and when he came back again a few days later he discovered that the candle was not lit. Pristley concluded that the plant does not produce air in the darkness and that it produced co2 and that light is essential for a plant to produce …show more content…
