Prokaryotes vs. Eukaryotes

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simple, unicellular organisms that lack a nucleus and membrane-bound organelles. They 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 and include plants, animals, fungi, and protists.

Front

What is a key difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have membrane-bound organelles, while eukaryotic cells do.

Front

Which type of cell has a cell wall?

Back

Both prokaryotic cells (most bacteria) and plant eukaryotic cells have a cell wall.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in both prokaryotic and eukaryotic cells.

Front

What is the oldest type of cell?

Back

Prokaryotic cells are considered the oldest type of cell, dating back over 3.5 billion years.

Front

Do prokaryotic cells have DNA?

Back

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

Front

What is a chloroplast?

Back

Chloroplasts are organelles found in plant cells and some protists that conduct photosynthesis.

Front

Can prokaryotic cells perform photosynthesis?

Back

Yes, some prokaryotic cells, like cyanobacteria, can perform photosynthesis.

Front

What is the role of the cell membrane?

Back

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