plasma membrane
Yes, the cell membrane can be seen clearly as a structure. The cell membrane is called the plasma membrane and is a barrier between the cell and its environment.
cell plate
Cytoplasm is the selectively permeable structure that separates intracellular material from extracellular material.
plasma membrane
The cell wall is a rigid supporting structure.
Proteins in plasma membranes help maintain the structure and regulate the functions of cells by serving as channels for molecules to enter and exit the cell, as well as facilitating cell signaling and recognition.
