Keep good stuff in, keep bad stuff out, and allow some exchange between the two sides in case the cell needs to let stuff in or out!

Also, the cell wall exists to maintain structural integrity.

What are the three main parts of a bacterial cell what does it do those parts do?

The three main parts of a bacterial cell are the cell membrane, the cytoplasm, and the genetic material (DNA). The cell membrane acts as a protective barrier, controlling the movement of substances in and out of the cell. The cytoplasm is a gel-like substance that houses various cellular components and facilitates metabolic processes. The genetic material, usually in the form of a single circular DNA molecule, carries the instructions for the cell's functions and reproduction.

What three things do all bacterial cells animal cells and plant cells possess?

All bacterial cells, animal cells, and plant cells possess a cell membrane, which regulates the entry and exit of substances; genetic material (DNA or RNA) that carries the information necessary for cellular functions; and ribosomes, which are essential for protein synthesis. While their structures and functions may differ significantly, these components are fundamental to the life processes of all cells.

Which cell can be composed of three layers the membrane the cell wall and the outer membrane?

A Gram-negative bacterial cell can be composed of three layers: the inner plasma membrane, the peptidoglycan cell wall, and the outer membrane. The outer membrane contains lipopolysaccharides and serves as an additional barrier, contributing to the cell's defense against environmental stresses and antibiotics. This layered structure is characteristic of Gram-negative bacteria, distinguishing them from Gram-positive bacteria, which typically have a thicker peptidoglycan layer and no outer membrane.
