In an old experiment, Jean Baptista van Helmont grew a plant in a pot that he filled with 200 pounds of soil. After several years, the plant grew to weigh 169 pounds. The amount of soil in the pot did not change; it still weighed 200 pounds. What conclusion can be drawn from this experiment?

A. Most of the weight gain in plants comes from the soil they are planted in.
B. Soil is not important to plants at all.
C. Plants produce carbon dioxide.
D. The weight gain in plants does not come from the soil they are planted in.

Answer :

Final answer:

The weight gain in plants does not come from the soil they are planted in.


Explanation:

The conclusion that can be drawn from this experiment is that the weight gain in plants does not come from the soil they are planted in. Jean Baptista van Helmont's experiment showed that even though the plant gained weight, the weight of the soil remained the same. This indicates that plants primarily gain their weight from sources other than the soil, such as water and carbon dioxide from the air.
