Which combining form denotes the cell?

• A. thromb/o
• B. cyt/o
• C. cerebell/o
• D. cerebr/o

Answer: (B)

The combining form for cell is cyt/o. It appears in terms like cytology (the study of cells) and cytoplasm (the material inside a cell), which shows its clear link to the cell itself. The other forms point to different structures or concepts: thromb/o relates to clotting (as in thrombosis or platelets), cerebell/o to the cerebellum, and cerebr/o to the cerebrum. So cyt/o is the form that denotes the cell.
