Prokaryotes vs. Eukaryotes

Front

What is a prokaryote?

Back

A prokaryote is a single-celled organism that lacks a membrane-bound nucleus and 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

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

Do prokaryotes have a cell wall?

Back

Yes, most prokaryotes, such as bacteria, have a cell wall.

Front

Do eukaryotes have a cell wall?

Back

Some eukaryotes, like plants and fungi, have a cell wall, while animal cells do not.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell and provides protection and structure.

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries genetic information in living organisms.

Front

What are ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA.

Front

What is a nucleus?

Back

The nucleus is a membrane-bound organelle that contains the cell's genetic material (DNA) and controls cellular activities.

Front

What are membrane-bound organelles?

Back

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