How are macromolecules transported?

They don't pass like ions, monosaccharides and aa. Their transport is mediated by vesicles known as bulk transport. Enables take in and out of macromolecules. Inward transportation known as endocytosis (enter of proteins and some viruses...) and phagocytosis (large molecules 1 microm and more) restricted to animal cells since plant cell wall and turgor pressure prevent this process. Last type is outer transport called exocytosis.
