No, large polar molecules cannot pass through the plasma membrane.
The cell membrane (or plasma membrane) shows semi-permeability. In short some substances, such as gases and small electrically-neutral molecules CAN pass, while others like glucose and other large polar molecules CANNOT pass. Although glucose and other large polar molecules cannot pass through the semi-permeable cell membrane, they may enter through the interior of transport proteins.
The three molecules that cannot easily pass through the membrane are large molecules, charged molecules, and polar molecules.
Large molecules such as proteins and nucleic acids cannot pass through the cell membrane.
Large polar molecules pass through the membrane by using specific transport proteins that facilitate their movement across the lipid bilayer.
Large molecules can enter a cell through endocytosis, where the cell membrane folds around the molecule, forms a vesicle, and brings it into the cell. This process allows the cell to take in nutrients, signaling molecules, and other substances that are too large to pass through the membrane directly.
Large molecules like proteins and nucleic acids have difficulty crossing the plasma membrane due to their size. Charged molecules or ions also face barriers crossing the membrane because of the hydrophobic nature of the lipid bilayer. Additionally, molecules that are not lipid-soluble may have difficulty passing through the membrane.
Molecules that are large, polar, or charged generally do not pass easily through the plasma membrane. These types of molecules require transport proteins to facilitate their movement across the membrane. Examples include glucose, ions, and water.
Large molecules such as proteins, polysaccharides, and nucleic acids are generally unable to pass through the plasma membrane without assistance from transport proteins or other mechanisms. The size and charge of these molecules prevent them from diffusing across the membrane's hydrophobic interior.
The plasma membrane is made from tightlypack phospholipids. The plasma membrane prevents polar molecules and large molecules from diffusing freely. Fatty (lipophilic) molecules can easily pass through. since cells often need water soluble materials such as water and sugars, transporters and pores need to be made out of proteins to let those molecules through. One of the most important pumps is the Na+/K+ ATPase pump which maintains gradients of sodium and potassium across the cell membrane

Large polar molecules and charged molecules cannot pass directly through the phospholipids of the plasma membrane because the phospholipid bilayer is impermeable to them. Instead, these molecules rely on specific transport proteins like channels or carriers to facilitate their movement across the membrane.

large polar molecules cannot pass through the membrane. only nonpolar and small polar molecules can pass through, and they only go from high to low concentration or else they need assistance from active transport.
