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 is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that contains organelles and is where many cellular processes occur.

Front

What are ribosomes?

Back

Ribosomes are molecular machines in cells that synthesize proteins by translating messenger RNA.

Front

Do prokaryotic cells have a cell wall?

Back

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

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.

Front

What is a nucleoid?

Back

A nucleoid is the region in a prokaryotic cell where the DNA is located, not enclosed by a membrane.

Front

What organelles are found in eukaryotic cells but not in prokaryotic cells?

Back

Eukaryotic cells have organelles such as the nucleus, mitochondria, and endoplasmic reticulum, which are not found in prokaryotic cells.

Front

How do prokaryotic and eukaryotic cells reproduce?

Back

Prokaryotic cells typically reproduce asexually through binary fission, while eukaryotic cells can reproduce both asexually and sexually.
