Organelle quiz review

Which of the following organisms is made up of prokaryotic cells?

• Plants

• Bacteria

• animals

• fungi

Answer explanation

Bacteria are the only organisms listed that consist of prokaryotic cells, which lack a nucleus. In contrast, plants, animals, and fungi are made up of eukaryotic cells, which have a defined nucleus.

Which type of cell has a nucleus?

• Prokaryotic cells

• Eukaryotic cells

• Both prokaryotic and eukaryotic cells

Answer explanation

Eukaryotic cells have a nucleus, which contains their genetic material. In contrast, prokaryotic cells lack a nucleus; their DNA is not enclosed within a membrane. Therefore, the correct answer is eukaryotic cells.

Eukaryotic cells have membrane bound organelles.

• TRUE

• FALSE

Answer explanation

Eukaryotic cells are characterized by having membrane-bound organelles, such as the nucleus, mitochondria, and endoplasmic reticulum, which compartmentalize cellular functions. Therefore, the statement is TRUE.

Which of the following organisms is made up of eukaryotic cells?

• Plants

• Bacteria

• None of the above

Answer explanation

Eukaryotic cells, including plant cells, have membrane-bound organelles such as the nucleus and mitochondria. Bacteria are prokaryotic and lack these structures, making 'Plants' the correct choice.

Which type of cell has a cell membrane?

• Prokaryotic cells

• Eukaryotic cells

• Both prokaryotic and eukaryotic cells

Answer explanation

Both prokaryotic and eukaryotic cells have a cell membrane. The cell membrane is essential for maintaining the integrity of the cell and regulating the movement of substances in and out.

What type of cell is pictured below?

• Prokaryotic

• Eukaryotic

Answer explanation

The cell depicted is eukaryotic, characterized by a defined nucleus and membrane-bound organelles, distinguishing it from prokaryotic cells, which lack these features.

All eukaryotic organisms are multicellular.

• TRUE

• FALSE

Answer explanation

The statement is FALSE because not all eukaryotic organisms are multicellular. Many eukaryotes, such as yeast and certain algae, are unicellular.

The DNA of these cells is circular and not found within a nucleus.

• 1. Prokaryotic cells

• Eukaryotic cells

• Both prokaryotic and eukaryotic cells

Answer explanation

Prokaryotic cells have circular DNA that is not enclosed within a nucleus, distinguishing them from eukaryotic cells, which have linear DNA contained in a nucleus. Therefore, the correct answer is prokaryotic cells.

Which type of cell has a cytoplasm?

• Prokaryotic cells

• Eukaryotic cells

• Both prokaryotic and eukaryotic cells

Answer explanation

Both prokaryotic and eukaryotic cells contain cytoplasm, which is the gel-like substance within the cell membrane that houses organelles and is essential for cellular processes.

What type of cell is pictured below?

• Prokaryotic cell

• Eukaryotic cell

Answer explanation

The cell depicted is a prokaryotic cell, characterized by the absence of a nucleus and membrane-bound organelles. This distinguishes it from eukaryotic cells, which have a defined nucleus and organelles.
