The prokaryotic cells are represented by bacteria, blue-green algae, mycoplasma and PPLO (Pleuro Pneumonia Like Organisms). They are generally smaller and multiply more rapidly than the eukaryotic cells.
Prokaryotes have a cell wall surrounding the cell membrane except in mycoplasma. The fluid matrix filling the cell is the cytoplasm. There is no well-defined nucleus. The genetic material is basically naked, not enveloped by a nuclear membrane. In addition to the genomic DNA (single chromosome/circular DNA), many bacteria have small circular DNA outside the genomic DNA. This smaller DNA is called plasmids. No organelles, like the ones in eukaryotes, are found in prokaryotic cells except for ribosomes. Hence statement 1 is not correct.
The eukaryotes include all the protists, plants, animals and fungi. In eukaryotic cells, there is an extensive compartmentalisation of cytoplasm through the presence of membrane-bound organelles. Eukaryotic cells possess an organised nucleus with a nuclear envelope. Hence statement 2 is not correct. In addition, eukaryotic cells have a variety of complex locomotory and cytoskeletal structures. Their genetic material is organised into chromosomes. All eukaryotic cells are not identical. Plant and animal cells are different as the former possess cell walls, plastids and a large central vacuole which are absent in animal cells. On the other hand, animal cells have centrioles which are absent in almost all plant cells.
