Nucleoli are usually single or multiple homogeneous spheres, which are the most prominent structures in interphase nuclei of eukaryotic cells. The size, shape and number of nucleoli vary with biological species, cell types and cell metabolism. In protein, cells with strong synthesis ability and active growth, such as secretory cells and oocytes, have large nucleoli, accounting for 25% of the total cell nucleus volume, while cells without protein synthesis ability, such as muscle cells and dormant plant cells, have small nucleoli.
