If a cell undergoes nuclear division (mitosis or meiosis) but not cytoplasmic division (cytokinesis), the product is a multinucleate cell. This means the cell will have multiple nuclei within a single cytoplasm.

Here's why:

* Nuclear division (mitosis or meiosis) results in the duplication and separation of the chromosomes, leading to two (or four in meiosis) complete sets of genetic material.

* Cytoplasmic division (cytokinesis) is the process where the cytoplasm divides, ultimately forming two separate daughter cells.

If cytokinesis doesn't happen, the nuclei remain within the same cytoplasm, creating a cell with multiple nuclei. This is not a typical condition for most cells, but it can occur in some situations.
