Before I begin, please note that bacteria can possess many structures and their structural Biology can be just as complex as their eukaryotic counterparts. It's become commonplace for many general biology textbooks, and even more complex textbooks (which is scary), to underscore the structural complexity of bacteria. Now that I've gotten that out of the way, here are two structures common to many bacterial cells.
1. Cell wall - provides structural support to the cell and resists internal turgor pressure; composed of peptidoglycan (murein), which is itself composed of alternating subunits of N-acetylglucosamine (NAG) and N-acetlymuramic acid (NAM). These "chains" of alternating subunits are cross-linked by peptide bridges. Despite what you might think, the cell wall is NOT a very good barrier, as it is more like a meshwork than an impenetrable forcefield. Some bacteria, such as those belonging to the class Mollicutes (e.g., Mycoplasma species) do not possess cell walls.
2. Flagella - these appendages are used for locomotion; composed of flagellin subunits and are powered by a flow of protons (or even sodium, as is the case in some Archaea) across the flagellar motor.

How do antibiotics work to target bacteria without causing harm to the surrounding human cells?
Antibiotics work by targeting specific structures or processes in bacteria that are essential for their survival, such as cell wall formation or protein synthesis. These structures or processes are not present in human cells, so the antibiotics are able to selectively kill the bacteria without harming human cells.
Which structure can be seen through a microscope?
Structures that can be seen through a microscope include cells, bacteria, fungi, blood cells, and tissues. These structures are magnified to allow for detailed observation and analysis.
Are bacteria cells unicelluar or multicellular?
Bacteria cells are unicellular, meaning they are made up of a single cell. They do not form multicellular structures like tissues or organs.
Do Eukeryotic cells have mesosomes?
No, mesosomes are not present in eukaryotic cells. Mesosomes are structures found in bacterial cells and are believed to play a role in cell division and respiration. Eukaryotic cells do not have the same type of membrane-bound organelles as bacteria.
What are small two-part structures in cells that make proteins?
small, two part structures in cells that make protiens
Which structures are found in plant cells and bacteria cells but not in animal cells?
Cell Walls
What cellular structures do plants have that animal cell do not have?
The cell wall is a structure that plant cells, bacteria cells, and fungal cells have but animal cells do not.Chloroplasts are organelles that plant cells have but bacteria cells, fungal cells, and animal cells do not.
Single bacteria cells split into what two cells?
When bacteria divide through binary fission, one cell becomes two daughter cells. This process involves the replication of DNA, elongation of the cell, and ultimately splitting into two genetically identical daughter cells.
What single cell split into two cells?
They split into two bacteria cells!
How do antibiotics work to target bacteria without causing harm to the surrounding human cells?
Antibiotics work by targeting specific structures or processes in bacteria that are essential for their survival, such as cell wall formation or protein synthesis. These structures or processes are not present in human cells, so the antibiotics are able to selectively kill the bacteria without harming human cells.
What are 6 main structures found in a bacteria cells?
There are not 6 but 5 main structures found in bacterial cells. They are DNA, cell membrane, ribosomes, surface layer and the cell wall.
Which structure can be seen through a microscope?
Structures that can be seen through a microscope include cells, bacteria, fungi, blood cells, and tissues. These structures are magnified to allow for detailed observation and analysis.
What two cell structures do protists have that bacteria does not?
Protists have membrane-bound organelles, such as a nucleus and mitochondria, which are not present in bacteria. Additionally, many protists possess a complex cytoskeleton that aids in maintaining cell shape and facilitating movement, a feature that is generally absent in bacterial cells. These structures contribute to the greater complexity and diversity of protists compared to bacteria.
There are two cells that have no nucleus what are they?
Red Blood Cells in eukaryotes Bacteria Cells in prokaryotes
When bacteria is divided into cells is called?
For reproduction, Bacteria undergo the process of binary fission. In this, the cell divides into two identical cells which makes them to function as two different cells from thereon.
Are bacteria cells unicelluar or multicellular?
Bacteria cells are unicellular, meaning they are made up of a single cell. They do not form multicellular structures like tissues or organs.
Which cells are prokarotes?
There are two types. They are bacteria and arche bacteria
