1.2 Syllabus
S1. Drawings of the ultrastructure of prokaryotic cells based on electron micrographs.
Prokaryotic cells (Bacteria): It is a unicellular organisms with simple and non-compartmentalized structure. It is also smaller than eukaryotes.
Short Notes:
-Cell wall: Protection and pressure maintenance
-Cell membrane (Plasma membrane): Transport of materials
-Cytoplasm: Contains mediums (enzymes, food...) for cellular process
-Ribosomes: Protein Synthesis
-Nucleoid: DNA containing area not enclosed by membrane
-Plasmid: Extra genetic material
-Pili: Attachment
-Flagellum: Movement

A2. Prokaryotes divide by binary fission
-All living organisms need to produce new cells
→ Used for asexual reproduction. Single circular chromosome is replicated and 2 copies of chromosome move to opposite ends of the cell.
→ Division of cytoplasm cell proceeds quickly and each daughter cells contain 1 copy of chromosome which is genetically identical.

S2. Drawings of the ultrastructure of eukaryotic cells based on electron micrographs
Animal Cell:
Plant Cell:
Animal Cell VS Plant Cell
Single Membrane VS Double Membrane
U1. Prokaryotes have a simple cell structure without compartmentalization.
U2. Eukaryotes have a compartmentalized cell structure.
Prokaryote vs Eukaryote
