Answer: Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. Plants give off both oxygen and water as photosynthetic byproducts. ... Plants also use diffusion to move molecules around the cell and between cells. A common form of diffusion within the plant is osmosis, where chemical products move through semipermeable membranes from areas of higher to lower concentration.
Hope this helps..... Stay safe and have a Merry Christmas!!!!!!! :D
