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. Based on your knowledge of
photosynthesis, how did the plant gain most of its weight?
A. The plant gained weight by absorbing nutrients from the soil.
B. The plant gained weight by producing oxygen and storing it.
C. The plant used carbon dioxide to make organic compounds like
glucose, which increased the plant's weight.
D. The plant made carbon dioxide from organic compounds like
glucose, which increased the plant's weight.

C. The plant used carbon dioxide to make organic compounds like glucose, which increased the plant's weight.

Explanation:

Plants are mostly autotrophic organisms i.e. have the ability to make their own food via the process of photosynthesis. The food, which s in the form of sugars makes up their biomass. Plants use carbon dioxide (CO2) in the presence of sunlight to make organic compounds such as glucose, which is necessary for growth.

Hence, according to this question, the plant in a pot filled with 200 pounds of soil gained weight and increased to 169 pounds because the plant used carbon dioxide in the process of photosynthesis to make organic compounds like glucose, which increased the plant's weight.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
