🧫 Anatomy of a Bacterial Cell (Prokaryote)

What is a nucleoid in a bacterial cell?

It is a region without a nuclear membrane that contains the circular bacterial chromosome (DNA).

What are plasmids in bacteria?

Plasmids are small, circular, double-stranded DNA molecules that are not essential for normal bacterial growth.

What advantages do plasmids provide to bacteria?

Plasmids can provide advantages such as antibiotic resistance, tolerance to toxins and metals, and special metabolic enzymes.

Why are plasmids used in genetic engineering?

Plasmids are used in genetic engineering because they are easy to manipulate and transfer between cells.

What is the function of ribosomes in a bacterial cell?

Ribosomes are the site of protein synthesis.

What is the cytoplasm in a bacterial cell?

The cytoplasm is the fluid interior of the cell.

What is the glycocalyx in a bacterial cell and what is its function?

The glycocalyx is a sticky outer layer (capsule/slime) used for protection and attachment.

What is the function of the cell wall in bacteria?

The cell wall gives structure and prevents cell lysis.

What is the role of the cytoplasmic membrane in bacteria?

The cytoplasmic membrane regulates the entry and exit of substances.

What are inclusions in a bacterial cell?

Inclusions are storage sites for nutrients or compounds.

What is the function of a flagellum in bacteria?

A flagellum is used for locomotion or movement.

What is a key difference between prokaryotic and eukaryotic cells regarding their nucleus and DNA?

Prokaryotes lack a nucleus and membrane-bound organelles. Their DNA is circular and found in the nucleoid, not enclosed, unlike eukaryotic DNA.
