Plz cause i don’t think this isn’t right at all

From left to right side

Explanation:

Diffusion is the process in which molecules move from a place of higher concentration to a place of lower concentration until a point comes when the concentration of the molecules is balanced in the both areas.

Now, if we look at the diagram, we see that molecules are highly concentrated on the left side, and next to that side is a semi permeable membrane through which they are getting diffused into the right side of the cell.

So, looking at it, it is very clear that molecules will move from left side (the most concentrated side) to te right side (the less concentrated side).

Hope it help!
