      Osmosis – diffusion of solvent (for simplicity sakes let’s say water) through cell membrane from a high concentration to low concentration untill there is equal concentration on either side (equilibrium).

      Diffusion – same idea but molecules and particles traveling from high concentration through the membrane to low concentration until they are equal in concentration (equilibrium).

      I know you are in grade 9 so those definitions may be confusing, I hope this somewhat watered down version makes sense.

      if you are higher than 9th grade, you may also want to take into consideration how the processes occur. Osmosis is a mix of simple diffusion of water(through the lipid bilayer) and facilitated diffusion of water(through water channels=acquaporins).
      Diffusion may be either simple, facilitated, or a mix between the two, like in case of water(although this last possibility is rare).
      Cheers
