Prokaryotic or Eukaryotic?
Answers:
1. Prokaryotic—no nucleus, no organelles
2. Eukaryotic—plant cells, green discs are
chloroplasts (organelle)
3. Eukaryotic—complex, contains a nucleus,
many organelles
4. Prokaryotic—small, simple, no organelles are
seen
5. Prokaryotic—small, simple, no organelles are
seen
6. Eukaryotic—unicellular, organelles present
Summary for Types of Cells Notes
• Prokaryotes:
– NO nucleus
– Bacteria
– Simple, small
• Eukaryotes:
– HAS a nucleus &
organelles
– Anything BUT bacteria
(YOU are EUkaryotic!)
– Complex, larger
Cells fall into two broad categories
depending on whether they contain a
nucleus.

•
“endo” = inside of
“sym” = together
“biotic” = living
“theory” = scientific explanation based on
scientific evidence
…Put that all together and you get…
Endosymbiotic Theory
• The theory that the eukaryotic cell is
actually composed of prokaryotic cells
– One prokaryotic cell living inside of another
prokaryotic cell, made a more complex cell called
the eukaryotic cell
• Organelles were once independent
prokaryotes
