The differences between these two groupings has to do with the presence or absence of a nucleus and cell organelles. Prokaryotic organisms lack a nucleus. They possess DNA material but it is not enclosed within a membrane system called the nucleus. These organisms also lack cell organelles such as chloroplasts or mitochondria. Organism included in the prokaryotes are the bacteria and blue-green bacteria.
Eukaryotic organisms posses the nucleus and cell organelles.
If a cell wall is present it is not of the peptidoglycan type. Organisms included as eukaryotes are members of the kingdoms Protista, Animals, Plants and Fungi. Eukaryotic structure of plants differs from other eukaryotic organisms in that plant have a cell wall, chloroplasts, and large vacuole. The plant cell is divided into the cell wall and the protoplast. Cell wall is the rigid structure that surrounds the plant cell.
