Diffusion is a process during which molecules or ions move from a region of (the options are) SELECT--- downhigherlowerselectivelytotallyup concentration to a region of (the options are) SELECT--- downhigherlowerselectivelytotallyup concentration. The particles move (the options are) SELECT--- downhigherlowerselectivelytotallyup a concentration gradient. Osmosis is similar, but a (the options are) SELECT--- downhigherlowerselectivelytotallyup permeable membrane separates two areas of different concentration. The membrane found just inside a plant cell wall is like this. The cell wall itself is (the options are) SELECT--- downhigherlowerselectivelytotallyup permeable.
