Often just one micron long,
(Prokaryotic cells!)
These cells have no nucleus.
(Prokaryotic cells!)
Simplest cell type in this song.
(Prokaryotic cells!)
Some reside within our guts. (Prokaryotic cells!)

CHORUS:
Prokaryotic, eukaryotic: two main types of cells.
(Prokaryotic, eukaryotic: two main types of cells.)

Other cells have organelles:
(Eukaryotic cells!)
Little rooms for different tasks.
(Eukaryotic cells!)
Chloroplasts trap light quite well;
(Eukaryotic cells!)
Lysosomes dispose of trash.
(Eukaryotic cells!)

CHORUS

Covered with a layer of fat,
(Both main types of cells!)
Holding ribosomes inside.
(Both main types of cells!)
These cells can be round or flat.
(Both main types of cells!)
These are cells that can divide.
(Both main types of cells!)
