Prokaryotic vs. Eukaryotic Cells

Prokaryotic and Eukaryotic Cells There are two fundamental types of cells: prokaryotic and

eukaryotic. Prokaryotic cells: Lack internal membrane-bound organelles. Organisms are known

as prokaryotes. Bacteria (kingdom Prokaryota) are prokaryotes. Eukaryotic cells:

Have a prominent nucleus and numerous membrane-bound organelles. Organisms are known as eukaryotes.

Protista, Fungi, Plantae, and Animalia are eukaryotes.

Cell Size Most cells fall within a range of 1-100 μ

μm in diameter. Prokaryotic cells are smaller than eukaryotic cells. Prokaryotic cells:

1-10 μ μm Eukaryotic cells: 10-100
