Before scientists understood the process of photosynthesis, they were at a loss to explain how plants could grow and increase their mass so dramatically from what appeared to be a steady diet of water. A 17th-century Flemish chemist named Jean Baptista van Helmont thought plants “extracted” the bulk of their food from soil (Van Helmont, 1841). Other scientists assumed plants gained their weight and size from carbon dioxide, while others assumed that water alone gave plants their heft.

None of these explanations, however, held up when tested experimentally. In test after test, mass loss by soil, water, and even carbon dioxide didn’t measure up to the mass gained by a growing plant. It wasn’t until Joseph Priestley’s experiments a century later that scientists began to suspect sunlight as the major contributor to a plant’s growth. – source

Photosynthesis is a symbiotic relationship between plants and microorganisms and involves photosynthesis, which allows plants to use energy from the sun, and water exchange between the plants and the water in the soil. Photosynthesis requires carbon dioxide (CO 2 ), water (H 2 O), and a few other necessary elements. Plants release water into the soil to provide the microorganisms with the carbon and oxygen they need to grow. Microorganisms, in turn, use the carbon and oxygen to produce the sugars that they then transfer to the plants. This transfer of food from the microorganisms to the plants occurs over many years.

Water is a necessary element in the water exchange process because it is what the plants need to produce sugars and oxygen. The carbon dioxide is removed from the water when the plants are harvested. If the water was not present, the microorganisms would die
