Prokaryotic Cell Biology Quiz

What are the main components of a prokaryotic cell's structure?

• Cell wall, cell membrane, cytoplasm, ribosomes, and genetic material

• Flagella, cilia, centrioles, endoplasmic reticulum, and lysosomes

• Chloroplasts, vacuole, cell wall, cell membrane, and cytoplasm

• Nucleus, endoplasmic reticulum, Golgi apparatus, lysosomes, and mitochondria

Describe the function of the cell wall in prokaryotic cells.

• Stores genetic material

• Facilitates cellular communication

• Regulates the entry and exit of substances

• Provides structural support and protection

Explain the role of ribosomes in prokaryotic cells.

• DNA replication

• Energy production

• Protein synthesis

• Cell wall formation

How is genetic material organized in prokaryotic cells?

• In a single circular chromosome located in the nucleus

• In multiple linear chromosomes located in the nucleus

• In a double circular chromosome located in the nucleoid region

• In a single circular chromosome located in the nucleoid region

What is the function of plasmids in prokaryotic cells?

• Storing energy for the cell

• Carrying genes that provide advantages such as antibiotic resistance or the ability to metabolize certain nutrients

• Regulating cell division

• Producing ATP for cellular respiration

Describe the process of binary fission in prokaryotic cells.

• The process of binary fission involves the fusion of genetic material from two different cells.

• Binary fission is a process that only occurs in eukaryotic cells.

• The process of binary fission involves the replication of the genetic material, elongation of the cell, and division into two daughter cells.

• During binary fission, the cell divides into three daughter cells instead of two.

What is the typical size range of prokaryotic cells?

• 10 to 50 micrometers

• 0.001 to 0.005 micrometers

• 5 to 10 micrometers

• 0.1 to 5.0 micrometers

Explain the function of flagella in prokaryotic cells.

• They are involved in protein synthesis.

• They are used for locomotion and movement.

• They are used for storing nutrients.

• They are used for photosynthesis.

How do pili contribute to the survival of prokaryotic cells?

• Pili aid in adhesion, genetic exchange, and movement.

• Pili help in photosynthesis

• Pili are used for energy storage

• Pili are involved in waste removal

What is the role of the cell membrane in prokaryotic cells?

• It is involved in protein synthesis.

• It provides structural support and protection.

• It regulates the entry and exit of substances.

• It stores genetic material.
