What was the design flaw of van helmonts experiment?
Van Helmont's experiment, which aimed to demonstrate that plants gain mass primarily from water, had a significant design flaw in that he did not account for the role of soil nutrients or other environmental factors. He placed a willow tree in a sealed container with only water, failing to consider that the tree also required minerals and nutrients from the soil for growth. This oversight led to an incomplete understanding of plant growth processes, as he attributed the increase in the tree's mass solely to water intake. Consequently, his conclusions were misleading regarding the sources of plant mass.

What was wrong about Van helmonts conclusion that when plants grow their increase mass on some water?
Van Helmont concluded that the mass gained by a plant during growth came solely from water, based on his experiment with a willow tree. However, he overlooked the role of soil nutrients and carbon dioxide from the air in the growth process. Modern understanding reveals that plants also absorb carbon from CO2 during photosynthesis, contributing significantly to their biomass. Thus, attributing the increase in mass solely to water was an incomplete assessment of plant growth.

Who are three scientists that contributed to our knowledge on photosynthesis?
Three scientists that contributed to our knowledge on photosynthesis are: Jan Ingenhousz, who discovered the role of sunlight in photosynthesis. Melvin Calvin, who elucidated the Calvin cycle, the process by which plants fix carbon dioxide during photosynthesis. Rudolph A. Marcus, who developed the theory of electron transfer reactions in photosynthesis, explaining the mechanism by which plants convert light energy into chemical energy.

Did the result of the experiment support van Helmont and beliefs?
The result of the experiment did not support van Helmont's beliefs. Instead of coming from water, the increase in the plant's mass was due to the absorption of nutrients from the soil.
