A bacterium has a cell membrane, not a cell wall.
This word is singular. One cell is the answer.
Bacterium is a prokariyote.Others are eukariyotic cells.
There are many kinds of critters with only one cell. The bacterium is a common one.

Bacterium has prokaryotic cells- cells that have no membrane-bounded organells.
No, bacteria are typically unicellular organisms, meaning they consist of a single cell. Some bacteria may form colonies or clusters, but each individual bacterium is a single cell.
intracellular.
Recalling endosymbiont-theory, many millions of years ago a cell was hungry and incorporated a bacterium. So the cell wrapped a lysosome around the bacterium and tried to digest it. But somehow the bacterium resisted and both found that it's an advantage for them to live in symbiosis. The cell fed the bacterium with nutrients and it reciprocated by donating his host energy (ATP). The proof lies within the form of the double membrane: the inner membrane has many wrinkles and resembles a bacterium while the outer membrane is smooth, like the mantle of a lysosome.
To infect an animal cell, a bacterium must penetrate the cell membrane, which acts as a barrier protecting the cell's interior. This process often involves the bacterium using specific surface proteins or structures, such as pili or fimbriae, to adhere to the cell surface. Once attached, many bacteria secrete enzymes or toxins that facilitate the disruption of the membrane or exploit cellular mechanisms to gain entry. Successful penetration allows the bacterium to access the cellular environment and replicate.

A white blood cell is the biggest then the anthrax bacterium then the influenza virus.Hope it helps! :)
