The phospholipid bilayer can reach out with its membrane, and engulf proteins and lipid incoming to the cell. This is known either as Pinocytosis or Phagocytosis- both are forms of endocytosis of the cell.
Pinocytosis is the ingestion of dissolved materials by endocytosis where the cell membrane invaginates and pinches off small droplets of fluid in a pinocytotic vescile.
In Phagocytosis, the cell membrane invaginates and pinches off, putting the proteins or lipids in a phagocyotic vacuole (endosome) and it fuses with lysosomes that digests the contents.

What else can I help you with?
Which cell organelle releases molecules in vesicles?
The Golgi apparatus is the cell organelle responsible for packaging and modifying molecules before releasing them in vesicles. These vesicles transport molecules to other parts of the cell or outside of the cell.
Do Golgi bodies produce protein?
The Golgi apparatus takes simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them into vesicles, and either stores them for later use or sends them out of the cell. It also builds lysosomes, creates complex sugars and sends them off in secretory vesicles.
Exocytosis vesicles develop from the membranes of which of the following structures?
Exocytosis vesicles develop from the trans-Golgi network or the endoplasmic reticulum in cells. These vesicles contain molecules that are transported to the cell membrane for release outside the cell.
Why do glands show the presence of more number of Golgi bodies and Endoplasmic Reticulum?
Remember that the purpose of Golgi bodies and the ER is to produce vesicles for transportation. Glands are secretory cells, therefore they will require a vast amount of Golgi bodies and ERs to function. Vesicles can transport other chemicals outside the cells via exocytosis.
What is The process by which large molecules leave the cell in vesicles that bud off the Golgi bodies is called?
The process by which large molecules leave the cell in vesicles that bud off the Golgi bodies is called exocytosis. This involves the fusion of the vesicle membrane with the cell membrane, releasing the contents outside the cell.
What structure tranports proteins?
Vacuole or vesicles are used to transport proteins and other molecules out of cells. These secretory vesicles are actually a part of Golgi bodies. After synthesis, protein undergoes modifications in ER and Golgi, where it packaged in those vesicles.

What packages materials in vesicles for export from a eukaryotic cell?
The Golgi apparatus packages materials into vesicles for export from a eukaryotic cell. Proteins and other molecules are modified, sorted, and packaged into vesicles to be transported to their destination within or outside of the cell.
In what organelle do molecules moves from the ER to the Golgi bodies?
vescies

Golgi bodies use what to transport molecules out of cell?
Membrane bound vesicles.
Is glycogen a functional protein?
Actualy glycogen is not a protein but it is a polymer of glucose molecules stored in animal bodies and used as energy source when needed.
What does the Golgi bodies does?
"The Golgi body and its vesicles function in the sorting, modifying, and packaging of macro-molecules that are secreted by the cell or used within the cell for various functions."
