How does phospholipids structure relate to the selective permeability of the plasma membrane? critical feature of the plasma membrane is that it is selectively permeable This a lows the plasma membrane to regulate transport across cellular boundaries a function essential Drag the labels to fill in the table. Use only white targets, Pink tables for pink targets, and blue labels for blue targets.

Solution

1. Hydrophobic   can cross easily No transport protein required

In lipid bilayer it has polar head and nonpolar tail. So, Non polar molecule can easily cross the membrane. It does not require any special mechanism for transport this molecules.

2. Polar molecules - Hydrophilic - Have difficulty to cross hydrophobic part - transport protein require for efficient transport.

Hydrophobic molecules hates the hydrophilic so it does not allow the polar molecules easily cross in the lipid bilayers.

3. Ions - Hydrophilic - Have difficulty to cross hydrophobic part - transport protein require for efficient transport.
