Answer:
Step-by-step explanation:
Endocytosis and exocytosis are both processes that are used by several types of cells, including both prokaryotic and eukaryotic cells. Endocytosis is the process by which cells take in materials from their environment by forming a vesicle (i.e. a closed sac) around the material, while exocytosis is the process by which cells release materials, such as proteins, hormones, or neurotransmitters, by fusing their membranes with the membranes of nearby cells or releasing the contents into the external environment. Both of these processes are essential for proper cell function and survival.
