Download Prokaryotes vs. Eukaryotes

Cells: Prokaryotes vs.
Eukaryotes!
Cells have evolved two
different stuctures:!
Prokaryote & Eukaryote!
Prokaryotes Bacteria Ex: E.coli and
Salmonella!
Archaea Eukaryotes Animals Plants Pro5sts Ex: Red Algae!
Fungi Ex: Yeast and Mushrooms!
Prokaryotes!
• 
• 
• 
• 
Most are bacteria!
VERY small!!
Single-celled (unicellular)!
NO nucleus (loose strands of DNA)!
These are prokaryotic !

head of a steel pin.!
Structures in Prokaryotic cells!
•  cell membrane: surrounds the
cell!
•  cytoplasm: inner liquid
filling!
•  DNA in one big loop!
•  Flagellum: helps cell move!
•  ribosomes: for building
proteins!
NO NUCLEUS!!
All of these structures found
in eukaryotes too!!
Prokaryote Energy!
•  Different types of Prokaryotes get
energy different ways!
–  Photosynthesis (Autotrophic)!
–  Pathogenic – feed on living things !
•  The kind that make you sick!!
–  Decomposers – feed on dead things!
Eukaryotes!
•  Have organelles!
•  Larger and more complex!
•  Have a nucleus (where
DNA is kept!)!
•  multicellular (more than
one cell) or unicellular!
•  Include animal and plant
cells!
Eukaryotes have Organelles!
•  ORGANELLE – membrane-bound cell part!
•  Mini “organs” that each have a special job
to do!
•  Located in cytoplasm!
Two Main Types of Eukaryotes!
•  Animal Cell!
"  
Plant Cell!
All eukaryotes keep their
DNA in a nucleus!
Eukaryotic Cell Specialization!
!
•  The whole cell can be specialized for
one job – this is how we can form
multicellular organisms!!
Ex: Sperm Cells specialized to
deliver DNA to egg cell!
!
Ex: Red blood cells - specially
designed to carry oxygen
throughout the body!
