Other Examples of Cell Nuclei Besides these two simple examples of cell nuclei, there are countless variations to these two general schemes in nature. Some cells merge together, creating large cells with multiple cell nuclei in each cell. Many organism have cells with more than one nucleus, including humans. Human muscle cells are multi-nucleated. Other organisms, like some fungi , exist with most or all of their cells being multi-nucleated. In some organisms, the process of cell division does not include the breakdown of the nuclear envelope. Instead, microtubules extend through the cell nucleus and directly manipulate the chromosomes and work to divide the nucleus. Evolutionarily, it is assumed that early organisms that developed nuclei had clear advantages over those without. Over the course of millennia, different strategies for managing and maintaining the cell nucleus have evolved. While the nucleus may seem like a more advanced form of life, don’t forget that prokaryotes , like bacteria and other single-celled life forms, are still some of the
