WebSome small molecules, such as water, can pass directly through the membrane through small gaps in between the phospholipids making up the lipid bilayer. Larger molecules, such as glucose, and charged partides, such as ions, cannot pass through these gaps. WebIf the pores in the selectively permeable membrane became larger, but still not large enough to let the sugar pass through, what would happen during osmosis in the U-shaped tube compared to what is shown in the figure? The final water levels would be the same as shown in the figure, but the solutions would reach near equal concentrations faster.
