Question

Which scientist concluded that most of a growing plant's mass comes from water?

Answer 1

Plants get most of their mass from water, which comprises 80 to 90 percent of their total weight.

Step-by-step explanation:

Water is the most important factor limiting terrestrial photosynthesis worldwide. When plants grow, they generally get bigger in both size and weight. However, the growth of plants is defined as an irreversible increase in size, not an increase in weight. The main source of a growing plant's mass is water, which comprises 80 to 90 percent of the plant's total weight. Plants absorb water from the soil through their roots and transport it up to the leaves through the xylem.
