Question

drag items from the left column to the correct order in the right column. highest permeability to least permeability of the plasma membrane water sodium ion oxygen

Explanation:

Small, non - polar molecules like oxygen can easily pass through the plasma membrane due to its lipid - bilayer structure. Water is also relatively permeable as it can pass through via simple diffusion and aquaporins. Sodium ions are charged and have lower permeability as they require ion channels or transporters to cross the membrane.

Answer:

1. Oxygen
2. Water
3. Sodium ion
