Cell Structure and Function
Cytoplasm
The cytoplasm is the internal "soup" of the bacterial cell, bounded on the outside by the cell envelope. It is mostly water, but contains bacterial inclusions.
Cell Membrane
The cell membrane protects the cell from its surroundings. It controls the movement of substances in and out of cells and consists of the phospholipid bilayer with embedded proteins.
Nucleus
The nucleus is located in the very center of the cell and serves as the control center. It is made up of the nucleolus, chromosomes, and is surrounded by the nuclear envelope.
Nuclear Envelope
The nuclear envelope surrounds the nucleus with a double membrane and multiple pores. The pores regulate the passage of macromolecules but permit free passage of
