The question is incomplete. The complete question is as fllows:
The peptidoglycan cell wall and the one or two membranes present also impart a three-dimensional shape to the bacterial cell. The overall shape and arrangement of bacteria are genetically determined, so that each genus of bacteria has a characteristic shape (round, rod, spiral, etc.) and arrangements of the growing cell population (individual cells, chains of cells, or clustered cells).
Bin 1 - Image of a single round bacterium.
Bin 2 - Image of a single rodishaped bacterium.
Bin 3 - Image of a cluster of round bacteria.
Bin 4 - Image of a string of rodishaped bacteria.
Bin 5 - Image of a vibrio (commaishaped) bacterium.
Bin 6 - Image of a corkscrewishaped spirochete bacterium.
Answer:
The cell wall is the outermost covering that lies outside the plasma membrane and not necessary to present in all the living organisms. Some bacteria, plant cells and fungus has the cell wall that maintains their shape and protect them during the harm environmental condition.
The bacteria on the basis of the shape of the cell wall is divided into the different categories. The round bacteria is circular in shape and cocci is included in the category of round bacteria. The bacilli is the rod shaped bacteria. Round bacteria may also present in group and staphylococci is included in this category. The bacteria that are in the string of rod shape is streptobacilli . Vibrio is a comma shaped bacteria. The bacteria can also be the cork screw in shape and spirochete is included in this category.
