cell with a total of 0.3 osmol/L is placed into a solution with a total of 0.2 osmol/L.  It is assumed that the osmotic particles cannot pass through the cell membrane. Answer the following true or false questions. 1. All particles will diffuse down a concentration gradient, that is, move from a high concentration into a lower concentration  2. Diffusion down a gradient happens because particles are constantly moving (Kinetic Theory) 3. When solvent particles move down a gradient through a membrane it is called osmosis
