What does the suffix -cyte mean?cellproteingerm cellPTT

The suffix "-cyte" is derived from the Greek "kytos" meaning "hollow, as a cell or container." In the context of biology and cellular biology, "-cyte" is used to denote a cell. It is used in the formation of names of cells, especially blood cells, such as erythrocyte and leukocyte. So, "-cyte" does not mean protein, germ cell, or PTT. It specifically refers to a cell.
