Bacteria are extremely diverse in shape and the environmental niches they populate.

While we often first think of the bacteria that cause disease, there are enormous numbers of bacteria types that are essential in our ecosystem.

For instance, bacteria that live in the soil convert nitrogen gas (from the air) into 'fixed nitrogen' by catalyzing a reaction that creates amino acids. Fixed nitrogen thereby become available in the soil and plants use it as a source of nitrogen. Then humans and other animals eat the plants and continue to use the nitrogen 'fixed' by soil bacteria to create proteins and other compounds essential to our type of life.

Bacteria are called 'procaryotes' - which means they have a type of cell which has no internal, organizing structures (called organelles). The DNA, RNA, ribosomes, and other important features of all cells, are simply in one compartment.

Bacteria are single-celled organisms and represent some of the least complicated forms of life on earth.

Bacterial cell is what makes up the bacteria itself.
If you want to ask about bacterial cell wall: the bacterial cell wall provides structural integrity to the cell. In prokaryotes, the primary function of the cell wall is to protect the cell from internal turgor pressure. Peptidoglycan is responsible for the rigidity of the bacterial cell wall and for the determination of cell shape.There are two main types of bacterial cell walls, Gram positive and Gram negative.

bacteria cell is a cell that is a living organism. it eats and poops and mates and dies. some are good for you like e. coli in your intestine.. it recycles dead carcas and dead plants into soil so plants cran grow and animals can eat plants and grows. some can make you sick because it contains poison (toxin) inside or outside its cell. there's alot of bacteria and it's everywhere.
