What is Bacterial cell ?

Small, single-celled organisms called bacteria exist. Nearly all areas of the world are home to bacteria, which are essential to its ecosystems. Some species can survive in environments with high pressure and temperatures. In fact, it's thought that there are more bacterial cells in the human body than there are human cells.

The cell wall creates a solid structure around the cell that is uniform in thickness and is what gives the cell its distinctive shape (rod, coccus, or spiral). The plasma (cytoplasmic) membrane is located inside the cell wall (or stiff peptidoglycan layer), and it is typically in close proximity to the wall layer.
