Most plant and animal cells are similar in some respects since they both have in common cytoplasm and nucleus.

In cell biology, the cytoplasm is the material within a living cell, excluding the cell nucleus. It comprises cytosol (the gel-like substance enclosed within the cell membrane) and the organelles – the cell's internal sub-structures.

The nucleus is a membrane-enclosed organelle found in eukaryotic cells.

The nucleus and the cytoplasm are two very different parts of cells, but they also work together in a number of key ways, particularly where protein production and cell division are concerned.
