Cells - Prokaryote Cell Structure

Question 1

What organelle protects bacterial cells

Answer 1

The cell capsule

Question 2

What is the cell capsule

Answer 2

A cell capsule is an area of polysaccharide surrounding the cell which protects pathogenic bacteria against white blood cells as it covers the antigens with sugar

Question 3

What is the cell wall

Answer 3

The cell wall is composed of polysaccharides and proteins and mentains the overall shape of the cell

Question 4

What is a bacteria cell wall made of

Answer 4

Murein

Question 5

What is the plasma membrane

Answer 5

The plasma membrane is a phospholipid bilayer with multiple proteins within the layer that are primarily responsible for the transport of molecules across the membrane

Question 6

What are the ribosomes

Answer 6

Ribosomes live in the cytoplasm and are have a grainy appearance in an electron microscope. Their purpose is translating genetic messages as messenger RNA (mRNA) into the production of proteins

Question 7

What are the pili

Answer 7

The pili are hollow, hair like structures that are made of protein that allow bacteria to attach to cells

Question 8

What is the name of the process at which pili attach to other cells

Answer 8

Horizontal gene transmission

Question 9

What is circular DNA

Answer 9

Circular DNA possesses the GI of the bacteria process of binary fission

Question 10

What is the flagella

Answer 10

The flagella is for mobility. It rotates by a motor that sits beneath the cytoplasmic membrane

Question 11

What is plasmid DNA

Answer 11

Possesses genes that may aid the survival of the bacteria in adverse conditions
