DNA and Cell Transport Quiz

What is the shape of the DNA molecule?

• Linear

• Double helix

• Circular

• Zigzag

Which of the following best describes the function of DNA in cells?

• DNA provides energy for cellular processes.

• DNA stores genetic information.

• DNA transports nutrients across the cell membrane.

• DNA acts as a structural component of the cell.

Explain how DNA replication is important for cell division.

• It ensures that each new cell receives a complete set of genetic instructions.

• It provides the energy needed for cell division.

• It helps in the removal of waste products from the cell.

• It assists in the transport of proteins across the cell membrane.

Match the following processes with their type of transport.

• Active transport process involving expelling substances

• Exocytosis

• Active transport process involving ion exchange

• Sodium-potassium pump

• Passive transport process involving water movement

• Endocytosis

• Active transport process involving engulfing substances

• Osmosis

Describe the process of osmosis in cells.

• Movement of water molecules from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane.

• Movement of solute molecules from an area of high concentration to an area of low concentration through a semi-permeable membrane.

• Movement of water molecules from an area of high solute concentration to an area of low solute concentration through a semi-permeable membrane.

• Movement of solute molecules from an area of low concentration to an area of high concentration through a semi-permeable membrane.

Differentiate between passive and active transport.

• Passive transport requires energy, while active transport does not.

• Passive transport does not require energy, while active transport does.

• Both passive and active transport require energy.

• Neither passive nor active transport require energy.

Match the following scenarios with their effects on a cell.

• A cell placed in an isotonic solution.

• 
• A plant cell in a hypotonic solution.

• 
• A cell placed in a hypotonic solution.

• 
• A cell placed in a hypertonic solution.
