Biology: Chapter 1: Cells: Prokaryotic and Eukaryotic
Prokaryotic (No nucleus)
- Very small in size, 1-10 micrometers
- Nuclear region does not have nuclear membrane
-Single chromosome present
-Nucleolus is absent
-Membrane bound organelles are absent
-Multiplication of cell is by fission or budding
-Cell wall present in plant cells
-Unicellular
-Example : Bacteria, Archaea
Eukaryotic (Has a nucleus)
-Much larger than prokaryotic cells. 10-100 micrometers
-Nucleus surrounded by double membrane layer (Nuclear envelope)
-More than one chromosome present
-Nucleolus present
-Membrane bound organelles present
-Cell division by mitosis or meiosis
-Multi-cellular
-Example: Animal and plant cells
