2.2 Prokaryotic & Eukaryotic Cells

What are the major types of cells?

• Prokaryotic & Eukaryotic

• Animal & Plant

• Bacterial & Archaeal

• Multicellular & Unicellular

Prokaryotic cells are characterized by which of the following features?

• They have a nucleus.

• They can be multicellular.

• They have no membrane-bound organelles.

• They are typically larger than eukaryotic cells.

What can be used to observe prokaryotic cells?

• Light microscope

• Transmission electron microscope

• Scanning electron microscope

• Both B and C

Which of the following is NOT a structural feature of bacteria?

• Single circular chromosome of double stranded DNA

• Membrane-bound organelles

• Cell wall

• Capsule

What is the outer covering of a bacterial cell composed of?

• Cell membrane, cell wall, and capsule

• Cell membrane, cell wall, and flagella

• Cell membrane, cell wall, and cilia

• Cell membrane, cell wall, and pili

How long have prokaryotic cells existed, according to the text?

• 1.5 billion years

• 2.5 billion years

• 3.5 billion years

• 4.5 billion years

What is the function of ribosomes in prokaryotic cells?

• For cell division

• For protein production

• For movement

• For adhesion

Why are prokaryotic cells considered the smallest, simplest, and most primitive living things?

• Because they have a complex structure with many membrane-bound organelles.

• Because they have a large size and complex DNA organization.

• Because they have a small size, lack membrane-bound organelles, and have existed for approximately 3.5 billion years.

• Because they are a recent evolutionary development.

What is the domain of eukaryotic cells?

• Archaea

• Bacteria

• Eukarya

• Prokarya

Which of the following is NOT a kingdom included in the domain Eukarya?

• Protists

• Fungi

• Archaea

• Plants
