Cells Structure and Function Quiz

What is the basic structural and functional unit of all living organisms?

• tissue

• molecule

• atom

• cell

Describe the difference between prokaryotic and eukaryotic cell structure.

• Prokaryotic cells are only found in plants, while eukaryotic cells are only found in animals.

• Prokaryotic cells have a nucleus and membrane-bound organelles, while eukaryotic cells lack a nucleus and membrane-bound organelles.

• Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

• Prokaryotic cells are larger in size compared to eukaryotic cells.

Explain the role of the cell membrane in maintaining cell homeostasis.

• Stores genetic information

• Regulates the movement of substances in and out of the cell

• Helps in cell division

• Provides energy for the cell

Name two organelles involved in protein synthesis and describe their functions.

• Mitochondria and Golgi apparatus

• Nucleus and lysosomes

• Cell membrane and cytoskeleton

• Ribosomes and endoplasmic reticulum

What are the main components of the cell membrane and their functions?

• DNA, RNA, and lipids; providing energy, storing genetic information, and cell communication

• Carbohydrates, nucleic acids, and water; providing energy, storing genetic information, and cell signaling

• Phospholipids, proteins, and cholesterol; providing structure, regulating passage of substances, and cell signaling

• Proteins, carbohydrates, and nucleic acids; providing structure, regulating passage of substances, and storing genetic information

Explain the process of passive transport across the cell membrane.

• Molecules move across the cell membrane with the use of energy

• Passive transport requires the assistance of transport proteins

• Molecules move across the cell membrane without the use of energy

• Passive transport involves the movement of molecules against the concentration gradient

Describe the role of the cell membrane in cell communication.

• Allows the passage of signaling molecules and controls reception of signals

• Only allows the passage of nutrients and water

• Has no role in cell communication

• Prevents the passage of signaling molecules and inhibits reception of signals
