Muscle cells in the mammalian heart are multinucleate, meaning that multiple nuclei are present in the cytoplasm of individual large cells. predict what is different about the cell cycle in a muscle cell.

Cell division is different in this type of multinucleated cells, in them there is mitosis but no cytosinesis or cytoplasm division. These muscle cells have nuclei in the periphery of the cell. In the life cycle of these cells there are successive divisions of all nuclei

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
