Staphylococci are described as forming irregular clusters resembling which fruit?

• A. Grapes
• B. Apples
• C. Oranges
• D. Lemons

Answer: (A)

Staphylococci appear as irregular, grape-like clusters because the cocci divide in multiple planes and remain attached after division, forming loose, clumped groups rather than neat chains. That clustered, bunches-of-grapes look is a classic way to describe their arrangement under the microscope. In contrast, organisms that divide in a single plane tend to form chains, which is why streptococci aren’t described as grapes. The other fruits wouldn’t accurately convey the true, irregular clustering pattern observed with staphylococci, whereas grapes perfectly capture that uneven, clumped appearance.
