Types of Cells: Prokaryotes vs. Eukaryotes

Basic Parts of ALL Cells

1. Plasma membrane• Serves as the outer boundary of the cell

Basic Parts of ALL Cells:

2. Cytoplasm• Fluid inside the plasma membrane that contains dissolved

molecules

3. Genetic Material• DNA that regulates the functions of the cell

But what makes cells different?

1. Size2. Complexity3. Presence of a nucleus• Nucleus = membrane-bound structure that

houses DNA4. Presence of organelles• Organelle = membrane-bound intracellular

structures with a specific function

Prokaryotes Eukaryotes

Size 0.1-10 μm 10-100 μm

Complexity Simple Complex

Presence of Nucleus Absent Present

Presence of Organelles Absent Present

Prokaryotic vs. Eukaryotic Cell

Picking apart the words…

• Prokaryote• “Pro” = before• “kary” = nucleus

• Eukaryote• “Eu” = true• “kary” = nucleus
