Backpack shaped microorganisms are called?

• A. Staphylococcus.
• B. Sarcina.
• C. Micrococcus.
• D. Diplococcus.

Answer: (B)

Backpack-shaped refers to how the cells arrange after division. Sarcina divides in three perpendicular planes to form cube-like packets of cocci. Those compact, cube-like clusters look like a small backpack under the microscope, which is why this arrangement is described as backpack-shaped. This cubical packing is distinctive for Sarcina, helping to distinguish it from other cocci forms: Staphylococcus forms grape-like clusters, Micrococcus often appears in tetrads or small irregular groups, and Diplococcus appears as pairs. So the backpack-shaped arrangement is a hallmark of Sarcina.
