-Bacteria and Cyanobacteria (photosynthetic bacteria) make up the 'Prokaryotae-Kingdom'.
- Example of a Prokaryotic Cell= A Bacterium
-They do not have a nuclei or other membrane- bound cell organelles such as a nuclear envelope and mitochondria.
-Prokaryotic cell means 'before the nucleus'
-Most prokaryotes are extremely small with diameters between 0.5 and 5μm.
-A cell wall is always present in prokaryotic cells
- They are all other living organisms that have cells that contain discrete membrane-bound organelles such as a nuclei, mitochondria and chloroplasts (in plants only).
-An example= A plant or animal cell
-Eukaryotic Cells means 'true nucleus'
-They are larger than prokaryotic cells with diameters of 20μm or more.
-Unlike the prokaryotes, not all eukaryotic cells have a cell wall
-Organisms with eukaryotic cells are called 'eukaryotes'
