Question

Rod-shaped bacteria are called
(A)Vibrio
(B)Cocci
(C)Bacilli
(D)Spirili

Answer 1

Hint: Rod-shaped bacteria is a genus of Gram-positive bacteria. These mostly include species of Bacillus bacteria. Bacillus bacteria are found in many different taxonomic groups of bacteria. These bacteria have a streamlined body.

Complete answer:
Rod-shaped bacteria are called Bacilli. The term is additionally accustomed to describe the shape (rod) of certain bacteria; and therefore the plural Bacilli is the name of the category of bacteria to which this genus belongs.

Additional Information: Bacteria are the single-cell organisms that neither come under the plants nor animals. they typically measure a few micrometers long and exist together in communities of millions. Most of the bacteria have a rigid cell membrane that gives a particular shape to the bacteria while protecting the interior components. Transformation is the commonest process of horizontal gene transfer and occurs when short DNA fragments are exchanged between donors and recipients. Transduction, which usually only occurs between closely related bacteria, requires the donor and recipient to transfer DNA by sharing cell surface receptors. Conjugation requires the physical contact between the cell walls of bacteria. The common categories of bacteria supported their shapes are:
Cocci- The bacteria that are oval or spherical in shape are included called cocci bacteria.
Bacilli (Rod-shaped)- These are rod-shaped cells that also like cocci, remain either single or attached to other cells.
Spiral- This group includes those bacteria that are either curved (comma-shaped) or helical-shaped.
The bacteria can range from curved to corkscrew-like spiral.
Vibrio- These are the comma-shaped bacteria.
So, the correct answer is ‘Bacilli’.

Note: Bacteria reproduce by binary fission. During this process, the bacterium, which may be a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates).
