What is the cell theory?

The scientific hypothesis that all living entities are made up of cells as the lowest functional unit is known as cell theory. According to cell theory, living things are made up of one or more cells, that the cell is the fundamental unit of life, and that new cells develop from existing cells. During cellular division, cells send genetic material to daughter cells. In terms of chemical makeup, all cells are fundamentally the same. Within cells, energy flow (metabolism and biochemistry) happens.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
