The cell membrane is made up of the lipid bilayer that has two layers of lipid molecule, check the image for correct answers and labels:
The lipid bilayer is a thin polar membrane made of two layers of lipid molecules. These membranes make a continuous barrier around all cells and protect the cell from external toxins and molecules that cause harm.
The lipid molecule contains two layers of lipid molecule and each lipid molecule has
- a polar head - hydrophilic in nature
- a nonpolar tail - hydrophobic in nature
In lipid bilayer of the cell, polar head groups face water, and hydrophobic tail faces each other and avoids water (check image for proper representation)
