Prokaryotes vs. Eukaryotes

Front

What is a prokaryote?

Back

A prokaryote is a single-celled organism that lacks a nucleus and membrane-bound organelles. Examples include bacteria and archaea.

Front

What is a eukaryote?

Back

A eukaryote is an organism whose cells contain a nucleus and membrane-bound organelles. Examples include plants, animals, fungi, and protists.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

The main difference is that prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What structures are found in both prokaryotic and eukaryotic cells?

Back

Both prokaryotic and eukaryotic cells contain cytoplasm, ribosomes, and a cell membrane.

Front

What is the function of the nucleus in eukaryotic cells?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

Do prokaryotic cells have a cell wall?

Back

Yes, most prokaryotic cells have a cell wall that provides structure and protection.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within eukaryotic cells, such as the mitochondria and endoplasmic reticulum, that perform specific functions.

Front

What is the size difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells are generally smaller (0.1 to 5.0 micrometers) than eukaryotic cells (10 to 100 micrometers).

Front

What is an example of a prokaryotic organism?

Back

Bacteria, such as Escherichia coli (E. coli), are examples of prokaryotic organisms.

Front

What is an example of a eukaryotic organism?

Back

Humans are an example of a eukaryotic organism.
