Based on the name of this organism, what can you predict about its morphology?
s. aureus is arranged in long chains.
s. aureus is spherical and arranged in clusters.
s. aureus is rounded-rod or oval shaped.
s. aureus is rod-shaped arranged in chains.

S. aureus is spherical and arranged in clusters

Explanation:

Staphylococcus aureus is a gram positive bacteria that forms a part of our body microbiota. It is usually found on skin and in upper respiratory tract. The genus name of this organism is Staphylococcus which tells a lot about its morphology. Cocci or coccus is the name given to bacteria who appear spherical. Staph points out to their arrangement which is in clusters. Had it been Streptococcus, it would mean that the bacteria were spherical and arranged in long chains. Similarly, Diplococcus would mean that the bacteria were spherical and arranged in groups of two. Hence from the name Staphylococcus aureus we can say that it is spherical and arranged in clusters.
