What is true about the structure or function of the plasma membrane a. large molecules often cross the plasma membrane while inside vesicles b. hydrophobic molecules keep the cell from getting too much water c. the bilayer structure forms a solid boundary that separates the cell from it's enviroment. d. it is made entirely of intergal proteins will mark brainliest

The right answer is A.

This phenomenon is called endocytosis.

Endocytosis is the mechanism of transport of molecules or even particles (viral, bacterial, etc.) to the inside of the cell.

Endocytosis can be performed by all eukaryotic cells except red blood cells.

This membrane mechanism (or quasi-membrane) is very important in the life of a cell, because it allows the internalization of specific molecules through specific receptors in the cell (and in particular in the cytosol), the molecule to "endocyte" being called ligand (eg, the transferrin (ligand) that will bind to specific membrane receptors of transferrin).
