Inside the cell: cell structure and function (Chapters 7,
6,11)
E. coli
A prokaryote Bird of
paradise
Paramecium Skin cells
A eukaryote
Multi-cellular organisms
Unicellular organisms (eukaryotes)
• cell structure/function
• cell division
• information coding (DNA)
• transcription/translation (RNA)
, Key concepts – cell structure/function
• There are two basic cell types: prokaryotic and eukaryotic
• The structure of individual cell components is closely correlated
with their function
• Eukaryotic cells contain extensive endomembrane system with
diverse specialized, compartmentalized functions
• Nucleus, ER, Golgi, Mitochondria
• Cytoskeleton = network of fibers - organises internal structure
and activities in cell
• Connections between cells (e.g. gap junctions, tight junctions) -
coordinate cell activities
Cells are very dynamic
