Based on the text, what can be concluded about cells that lack properly functioning mitochondria?

• They would be more efficient at removing waste.

  
  

• They would have an increased ability to divide.

  
  

• They would lack the energy to perform essential functions.

  
  

• They would have a stronger barrier against external toxins.

  
  

Based on the text, what inference can be made about the importance of the cell membrane's selective permeability?

• It allows the cell to produce energy more efficiently.

  
  

• It ensures that only necessary substances enter the cell, maintaining a stable internal environment.

  
  

• It speeds up the process of cell division.

  
  

• It prevents the nucleus from being damaged by external factors.

  
  

If a scientist is studying a disease that affects the cell's ability to divide, which organelle, based on the text, is most likely to be investigated?

• The mitochondria, because it provides the energy for cell division.

  
  

• The nucleus, because it controls cell division and contains DNA.

  
  

• The cell membrane, because it regulates the entry of substances needed for cell division.

  
  

• The lysosomes, because they clean up waste products that could interfere with cell division.
