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.

∙ 7y agoBacteria have some basic structures which include a cell membrane, a nucleoid (area of DNA) and cytoplasm. Some bacteria have addition parts. One is a flagellum which is a way for it to move. But not all have this.

What are small two-part structures in cells that make proteins?
small, two part structures in cells that make protiens
What are the structures of bacteria?
Structures of bacteria: Flagella PiliSex pilus Common pili or fimbriae Capsules Cell wallGram-positive bacteria Gram-negative bacteria Plasma membrane Ribosomes Inclusions Chromosome Plasmid
Two types of organisms whose cells do not have a nucleus?
Salmonella bacteria and bacillus bacteria are two types of cells that do not have a nucleus.
An extracellular matrix is produced by glycoprotein secretion by what?
An extracellular matrix is produced by glycoprotein secretion by animal cells. The simplest cells are the prokaryotic bacteria. Ribosomes are structures that are found within bacterial cells.
An organism whose cells lack a nucleus and some other cell structures?
An organism whose cells lack a nucleus and some other cell structures is called a prokaryotic organism. If the cells had a nucleus then the organism would be eukaryotic.
Which structures are found in plant cells and bacteria cells but not in animal cells?
Cell Walls
Single bacteria cells split into what two cells?
They split into two bacteria cells!
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.
Within which structures in humans are bacteria and dead cells removed from lymph?
Lymph Nodes
What are small two-part structures in cells that make proteins?
small, two part structures in cells that make protiens
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.
What single cell split into two cells?
They split into two bacteria cells!
What two structures surround cells?
The two structures that surround the prokaryotic cell are the cell membrane or plasma membrane and the cytoskeleton. All prokaryotic cells contain these.
What two structures are in plant cells but not in animals cells?
A cell wall and chloroplast!
Is ribosomes a bacteria?
Ribosomes are not bacteria. They are microscopic structures containing proteins and strands of RNA. They are located within the cytoplasm of plant and animal cells.
What two structures do all cells have?
nucleus, mitochondria
What are some parts onl y found in bacteria cells?
Bacteria cells are much simpler than other cells. Mostly they just lack most structures of higher cells. The only thing they have that others don't is circular DNA unenclosed by a nucleus.
