Comparing Prokaryotic and Eukaryotic Cells

What type of cells lack a nucleus or membrane-bound organelles?

What is the main structural difference between prokaryotic and eukaryotic cells?

• The main structural difference between prokaryotic and eukaryotic cells is that prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various membrane-bound organelles.

• Prokaryotic cells have a nucleus, while eukaryotic cells do not.

• Eukaryotic cells lack a cell membrane, while prokaryotic cells have one.

• Prokaryotic cells have multiple chromosomes, while eukaryotic cells have a single circular chromosome.

Which type of cells have a nucleoid region containing one DNA chromosome?

What is the function of the cytoskeleton in eukaryotic cells?

• Provides structural support and shape to the cell

• Stores genetic information

• Produces energy for the cell

• Synthesizes proteins

The main difference between prokaryotic and eukaryotic cells in terms of cell structure is:

• Presence of a nucleus in eukaryotic cells

• Size of the cells

• Shape of the cells

• Color of the cells
