Do all eukaryotic cells have nucleus and only one nucleus?
There are eukaryotic cells without a nucleus and others with more than one nucleus. Osteoclasts, the cells responsible for resorption of the osseous matrix, for example, are multinucleate cells; striated muscle fibers are multinucleate too. Red blood cells are an example of enucleated specialized cells.
all eukaryotic cells have a nucleus.. eu = true karyon= nucleus but It is possible that a cell has two nuclei... like paramecium has two nuclei.. micro and macro...But majority cell has only one nucleus.
