General characteristics of the cell membrane
Web5- Regulates cell growth. The cell membrane regulates the growth of cells through the balance between the processes of endocytosis and exocytosis. In endocytosis, lipids and proteins are removed from the cell membrane and incorporated into the cell. On the other hand, during exocytosis, vesicles containing lipids and proteins fuse with the cell ... WebThere are two main types of cells: Prokaryotic and Eukaryotic. These two types of cells are distinguished based on their cellular characteristics. Prokaryotic cells lack a true nucleus and other membrane-bound organelles while Eukaryotic cells have a nucleus and other membrane- bound organelles.
