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 size difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells are generally smaller than eukaryotic cells.

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

Which type of cell is more complex, prokaryotic or eukaryotic?

Back

Eukaryotic cells are more complex than prokaryotic cells due to their larger size and the presence of organelles.

Front

What evidence supports the idea that prokaryotes evolved before eukaryotes?

Back

Prokaryotes have no nucleus and fewer genes, indicating a simpler structure and function.

Front

What is the smallest unit of a living organism?

Back

The smallest unit of a living organism is a cell.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions, such as mitochondria and ribosomes.

Front

What is the primary difference in genetic material between prokaryotes and eukaryotes?

Back

Prokaryotes typically have a single circular DNA molecule, while eukaryotes have multiple linear chromosomes.

Front

How do prokaryotic cells reproduce?

Back

Prokaryotic cells reproduce asexually through a process called binary fission.
