Scientists Who Helped Develop the Photosynthesis Equation…

Intentionally left blank

Who conducted the experiment that determined plant growth needed water and was important part

of photosynthesis equation?

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.

Who conducted the experiment that determined plants release oxygen (O₂) and was an important

part of the photosynthesis equation?

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

Who conducted the experiment that determined plants need sunlight and was an important part of

the photosynthesis equation?

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

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

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
