3.4 - Ultrastructure of prokaryotic cells

What is the peptidoglycan cell wall

Cell wall around prokaryotic cells. Provides structure to cell and controls what enters and exits it.

What is a capsule

A protective layer on the outside of the cell that also helps with attachment to other surfaces

What is a plasmid

Circular DNA found in prokaryotic cells

What is the flagellum

A tail found on prokaryotic cells and a sperm cell used for motility

What is the pili

Hair-like structures attached to the outside of the cell that can be used to connect cells together and aid in the transfer of substances between them

What are 70s ribosomes

Ribosomes found in prokaryotic cells

What is the mesosome

A fold in the cell membrane used for respiration

What is circular DNA

Long free floating strand of DNA found in Prokaryotic cells

How is DNA in prokaryotes and eukaryotes different?

Prokaryotes have circular DNA that floats freely around the cell. Eukaryotes have linear DNA found in a nucleus

How are Ribosomes in each cell type different?

Prokaryotes have 70s ribosomes, eukaryotes have 80s ribosomes.
