How do cells deal with
substances that are too large to
pass through the cell membrane?
Biology
Unit V - Regulation
Endocytosis
Cells ingest large particles
How Does This Happen?
These external materials are enclosed by
a portion of the cell, which folds into itself
and forms a pouch
The pouch pinches off from the cell
membrane and becomes a membranebound organelle called a vesicle
Endocytosis
Exocytosis
Vesicles in the cytoplasm fuse with the cell
membrane and release their contents into
the cell’s external environment
