Description: The cell wall is a non-living, rigid structure outside the plasma membrane in plant cells and fungi. It is absent in Eukaryotic cells of animals
What is the unique characteristic of eukaryotic cells?
A eukaryotic cell has one unique characteristic that other cells do not. A Eukaryotic cell has a membrane-bound nucleus. The nuclear material in the cell or the DNA is contained within a double membrane.
