Prokaryotic cells vs Eukaryotic cells

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simple, unicellular organisms that lack a nucleus and membrane-bound organelles. Examples include bacteria and archaea.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and membrane-bound organelles. They can be unicellular or multicellular, such as plants, animals, and fungi.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

The main difference is that prokaryotic cells do not have a nucleus, while eukaryotic cells do.

Front

Do prokaryotic cells contain DNA?

Back

Yes, prokaryotic cells contain DNA, which is typically circular and located in a region called the nucleoid.

Front

Do eukaryotic cells contain DNA?

Back

Yes, eukaryotic cells contain DNA, which is linear and organized into chromosomes within the nucleus.

Front

What is a cell membrane?

Back

A cell membrane is a protective barrier that surrounds the cell, controlling the movement of substances in and out.

Front

Do both prokaryotic and eukaryotic cells have a cell membrane?

Back

Yes, both prokaryotic and eukaryotic cells have a cell membrane.

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.

Front

Can prokaryotic cells perform cellular respiration?

Back

Yes, prokaryotic cells can perform cellular respiration, but they do so in the cytoplasm or across the cell membrane, as they lack mitochondria.

Front

What is the size difference between prokaryotic and eukaryotic cells?

Back

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