Answer 8

Let me explain to you clearly: Diffusion and Osmosis are types of absorption in plants. DIFFUSION: Movement of solvent molecules from a region of higher conc. to a region of lower concentration until they are evenly distributed through available space. Gases such as Oxygen, carbon dioxide and nutrients like minerals move into or between the cells by diffusion. OSMOSIS: Movement of water molecules from a region of higher conc. to a region of lower concentration through a semipermeable membrane is called Osmosis.

Answer 9

C.Osmosis is a kind of diffusion that involves movement of water.
