27. Scientists Who Helped Develop the Photosynthesis Equation…

28. Intentionally left blank

29. Who conducted the experiment that determined plant growth needed water and was important part of photosynthesis equation?

30. Van Helmont CO2 + H₂O → Sunlight → C6H12O6 + O2 Van Helmont’s experiment concluded that the plant must have gotten its additional mass from H2O since that was all that the plant received.

31. Who conducted the experiment that determined plants release oxygen (O₂) and was an important part of the photosynthesis equation?

32. Priestly (Think: Priests put candles in churches) Priestly found the plant released OXYGEN from his experiment keeping mouse and flame alive. CO2 + H2O → Sunlight → C6H12O6 + O₂

33. Who conducted the experiment that determined plants need sunlight and was an important part of the photosynthesis equation?

34. Ingenhouz (“I” for light) Ingenhouz repeated Priestly’s experiment but tried it with and without sunlight to see if that was necessary. He found sunlight was an important part of photosynthesis. CO2 + H2O → Sunlight → C6H12O6 + O2

35. Who conducted the experiment that determined that photosynthesis had a cycle that created glucose from CO₂ and was an important part of the photosynthesis equation? ? GLUCOSE CO₂

36. Calvin Calvin came up with the Calvin Cycle and showed how plants take ATP and NADPH to change CO2 →C2H12O6 (glucose) CO2 + H2O → Sunlight → C6H12O6 + O2 GLUCOSE CO₂
