Considering the experiments of the Darwins, Boysen-Jensen, Paal, and Went, what do you conclude about phototropism?
A) We still do not know the mechanism for phototropism.
B) The substance that regulates phototropism is produced in the tips of plants, and causes the same response even when it comes from an external source (not from the same individual).
C) For a plant to bend toward a light source, the substance that regulates phototropism must be able to move into cells on the same side as the light source.
D) The substance that regulates phototropism is distributed throughout a plant equally, but cells on the side away from the light source are the only ones that respond to the substance.
