Prokaryotes
•Prokaryotic cells (pro = "former", karion = "nucleus") are evolutionarily
primitive.
•All bacteria are prokaryotic organisms.
•Prokaryotic cells can be described as:
•The size is small
•No membrane-bound, membrane-bound organelles Only have a cell or
plasma membrane.
•Genetic material is scattered in the cytoplasm
•Only the ribosome is found in the organelle.

Eukaryotes
Eukaryotes (Eu = "true", karyon = "nucleus") are unicellular and multicellular
organisms. Eukaryotic cells evolved from prokaryotic cells.
A eukaryotic cell can be described as:
• the genetic material of the cell is located in the nucleus surrounded by a double
membrane
• endomembrane systems such as membranous organelles, smooth and granular
endoplasmic reticulum, Golgi complex, and vesicles.
• Organelles that produce energy and take part in metabolism: mitochondria and
chloroplasts are found. Since the eukaryotic cell has many organelles, its size is also large.
• The reason for the large number of organelles in it is due to the complexity of eukaryotes'
life activities
• Organelles in eukaryotic cells are adapted to perform various functions.

Prokaryotes and Eukaryotes
Prokaryotes are organisms that do not have a fully
formed nucleus, and whose genetic information (singlestranded DNA) is located freely in the cell. They
appeared in ancient times. For example, they include
bacteria.
Eukaryotes are organisms with a fully formed nucleus,
where the genetic information (double-stranded DNA)
is located. In addition, they have well-formed organoids.
For example, they include plants, animals, fungi.

For a prokaryotic cell: cell wall, filament, capsule, mesosome, circular
DNA, cell membrane, ribosome
For a eukaryotic cell: cell membrane, nucleus, cytoplasm, mitochondria,
ribosomes, EPT, Golgi complex, plastids, DNA, nuclear membrane.
