What direction will the particles move across the cell membrane?

Simple Diffusion across the Cell(Plasma) Membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobicmolecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.

Right

Explanation:because the particles want to achive equalibrilium so both sides need to be equal.
