Prokaryotic and Eukaryotic Cells

Front

What are prokaryotic cells?

Back

Prokaryotic cells are single-celled organisms that lack a nucleus and membrane-bound organelles. They are generally smaller and simpler than eukaryotic cells.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and membrane-bound organelles. They can be single-celled or multicellular organisms.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

The main difference is that prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

Where is DNA located in eukaryotic cells?

Back

In eukaryotic cells, DNA is located in the nucleus.

Front

Do prokaryotic cells have DNA?

Back

Yes, prokaryotic cells have DNA, but it is not contained within a nucleus.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within a cell that are enclosed by membranes, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is a ribosome?

Back

Ribosomes are cellular structures that synthesize proteins. They can be found in both prokaryotic and eukaryotic cells.

Front

What is the function of the nucleus in eukaryotic cells?

Back

The nucleus houses the cell's DNA and is responsible for regulating gene expression and cell division.

Front

What is a cell wall?

Back

A cell wall is a rigid outer layer that provides support and protection to some cells, such as plant cells and prokaryotic cells.

Front

What is the significance of double-membrane organelles?

Back

Double-membrane organelles, such as mitochondria and chloroplasts, are important for energy production and photosynthesis in eukaryotic cells.
