Answers
Ello.. ✌✌
▶Plasma membrane is a fluid mosaic of lipids, proteins and carbohydrate.
▶The plasma membrane is impermeable to ions and most water-soluble molecules.
▶They cross the membrane only through transmembrane carriers.
▶These transmembrane proteins provide the cell with nutrients and create a electrical potential.
▶The cell membrane is primarily composed of a mix of proteins and lipids.
▶The plasma membrane is composed of a phospholipid bilayer which creates a barrier.
▶ Phospholipids are lipids with a phosphate group attached to them.
▶The phospholipids have one head and two tails.
▶The head is polar and hydrophilic, or water-loving.
▶The tails are nonpolar and hydrophobic or water-fearing.
