Is it true that as a cell gets larger it takes longer for a molecule that has entered the cell to reach the middle of the cell?
Yes, it is generally true that as a cell gets larger, it will take longer for a molecule to diffuse to the middle of the cell. This is because larger cells have a greater distance for the molecule to travel, leading to increased diffusion time. Additionally, larger cells may have more organelles and cellular structures that can obstruct the movement of molecules, further slowing down the process.
