Answer 1

Conditions that relate to the research of van Helmont are;

- Plant mass related to H2O

- Conclusions partly correct

Answer 2

The correct answer will be options-

1. plant mass related to H₂O

2.conclusions partly correct.

Step-by-step explanation:

Jan Baptist van Helmont was a physician, physiologist and chemist who is known for his experiments on plants.

He performed the experiments by placing a 5-pound willow plant in a pot with 90 kg of soil. He added no nutrients to the pot for the next five years except water and found that tree weighed about 169 pounds with the almost the same amount of soil in the pot. On the basis of this, he concluded that plants mass increased because of water only but he was not aware of the photosynthesis in which carbon is utilized from the air. So, his results were partly corrected.

Thus, the selected options are the correct answer.
