Question

The shape of bacterium is determined by its;

Select one:

a. Capsule

b. Nucleus

c. Nuclear membrane

d. Cell membrane

e. Cell wall​

Answer 1

Answer:

Bacterial cell shape is determined primarily by a protein called MreB. MreB forms a spiral band – a simple cytoskeleton – around the interior of the cell just under the cytoplasmic membrane. It is thought to define shape by recruiting additional proteins that then direct the specific pattern of bacterial cell growth.

Answer 2

The cell wall is the correct answer.

• The cell wall of bacteria usually determines its shape.

• In most bacteria, the cell wall of bacteria determines the shape of the cell.  

• Peptidoglycan (PG) is considered as the chief structural component of the cell wall in both Gram-positive bacteria and Gram-negative bacteria.

• Bacterial cell shape is determined principally by a protein which is known as MreB. MreB makes a spiral band which is a simple cytoskeleton – around the inner of the cell just under the cytoplasmic membrane.
