Historical Discovery Process
The chemical changes that occur during photosynthesis have been
investigated for the past 300 years. The general highlights of these
discoveries help us to understand the basic process of photosynthesis.
Three centuries ago people wondered where plants came from. They
knew that plants grew out of the ground, but how that happened was a
complete mystery to them. The first step in answering the question was
to plant a small tree in a large pot supported off the ground. They did this
so that the soil of the container was separated from the soil of the earth.
Only the dirt in the pot was available to the plant.
The people cared for the plant during one year. At the end of the year
the small tree had gained 100 kg. (The actual data from this experiment
have been changed to simplify the discussion.)
1. What do you think the experimenters considered as two possible
sources for the substances (matter) that became incorporated into new
tree growth?…
