We know that all living organisms are made of cells. Cells are the building blocks of life. They are so called because they are the basic functional and structural units of life.

If there are no living cells, there cannot be life on Earth. It will be a barren land somewhat like Mercury or Venus or Mars.

Now, there are two types of cells. There are Prokaryotic cells and there are Eukaryotic cell. We all learn about this basic thing in our schools. The question is, have you studied well enough?

In this Prokaryotic cells quiz, you get the chance to find out the extent of your knowledge. So, play! Don’t cheat!

Prokaryotic cells are the most primitive cells known to us.

prokaryotic cells quiz
Correct! Wrong!

Prokaryotic cells are the most primitive cells known to us. These are small and simple cells. The term Prokaryotic comes from the Greek words – ‘Pro’, which means ‘Primitive’ and ‘Karyon’, which means nucleus.

When did the prokaryotic cells first come into existence?

Correct! Wrong!

The first prokaryotic cells perhaps first came into existence some 3.5 billion years ago. For example, the giant colonies of extinct blue green algae or cyanobacteria which are technically known as Stromatolities are at least 3.5 billion years old. They existed in Western Australia.

Prokaryotic cells occur in which two?

Correct! Wrong!

Prokaryotic cells occur in Bacteria and archaea. A virus is a particle and not a cell. Archaea on the other hand are single-celled organisms complete different from bacteria.

A prokaryotic cell has what type of envelope system?

Correct! Wrong!

A prokaryotic cell is a one-envelope system that is organized in depth.

Which nuclear components are present in a prokaryotic cell?

Correct! Wrong!

The nuclear components that are present in a prokaryotic cell are the DNA molecules, RNA molecules and nuclear proteins.

Prokaryotic cells do not have cytoplasm.

prokaryotic cells quiz
Correct! Wrong!

False! Prokaryotic cells have cytoplasm. The cytoplasm surrounds the nuclear components.

The prokaryotic cells have a plasma membrane. What does the membrane enclose?

Correct! Wrong!

In a prokaryotic cell, the nuclear components are surrounded by cytoplasm. The cytoplasm in turn is enclosed in the plasma membrane. The nuclear components do not have any membrane enclosing them as in case of eukaryotes.

Which cytoplasmic organelles are present in the cytoplasm of a prokaryotic cell?

Correct! Wrong!

The cytoplasm of a prokaryotic cell does not have any cytoplasmic organelle.

The cytoplasm of a prokaryotic cell exhibits amoeboid or streaming movement.

Correct! Wrong!

No, the cytoplasm of a prokaryotic cell does not exhibit amoeboid or streaming movement.

The cell wall of a prokaryotic cell is cellulosic.

Correct! Wrong!

False! The cell wall of a prokaryotic cell is noncellulosic. In other words, the cell wall in prokaryotes do not have cellulose as a component.

In prokaryotes, the respiratory enzymes are carried by what?

prokaryotic cells quiz
Correct! Wrong!

The respiratory enzymes which are found in mitochondria in eukaryotic cells is carried by the plasma membrane in the prokaryotic cells.

Basal bodies and centrioles are absent in prokaryotic cells.

prokaryotic cells quiz
Correct! Wrong!

Yes, the basal bodies and centrioles are completely absent in prokaryotic cells.

A prokaryotic cell contains microtubules, microfilaments and intermediate filaments.

Correct! Wrong!

False! Microtubules, microfilaments and intermediate filaments (together known as cytoskeleton) are completely absent in a prokaryotic cell.

Nucleoli are absent in prokaryotic cells.

prokaryotic cells quiz
Correct! Wrong!

Yes, the nucleoli are completely absent in prokaryotic cells.

Histones are present in the chromosomes of prokaryotic cells.

Correct! Wrong!

No, histones are absent in the chromosomes of prokaryotic cells. Histones are basic proteins and they can be found in the chromosomes of only eukaryotic cells.

Flagellum is present in all prokaryotic cells.

Correct! Wrong!

Flagellum is present in some types of prokaryotic cells. A flagellum is a long whip-like protrusion that helps in cellular locomotion.

How do prokaryotic cells reproduce?

Correct! Wrong!

Prokaryotic cells reproduce asexually. The usual process they use is binary fission.

Prokaryotes cannot form colonies because they are strictly unicellular.

Correct! Wrong!

Prokaryotes are strictly unicellular but they can still form stable aggregate communities.

How many basic shapes do prokaryotic cells have?

Correct! Wrong!

Prokaryotic cells have various types of shapes. However, there are four basic shapes. They are: Cocci (spherical or ovoid), Vibrio (comma-shaped), Spiral bacteria (some rods twist into spiral shapes), Bacilli (cylindrical shape called rod).

What is the shape of DNA in prokaryotic cells?

prokaryotic cells quiz
Correct! Wrong!

The shape of DNA in prokaryotic cells is circular double-stranded.
