Which of the following best explains how membrane-bound organelles contribute to compartmentalization within eukaryotic cells?

• A. They allow for the separation of incompatible chemical reactions.
• B. They increase the surface area for photosynthesis.
• C. They facilitate the movement of the cell.
• D. They enable the cell to maintain a constant temperature.

Answer: (A)

Verified step by step guidance

1. Understand the concept of compartmentalization: In eukaryotic cells, compartmentalization refers to the division of the cell into distinct areas, each with specific functions, often facilitated by membrane-bound organelles.
2. Identify the role of membrane-bound organelles: These organelles, such as the nucleus, mitochondria, and chloroplasts, have membranes that create separate environments within the cell.
3. Consider the separation of chemical reactions: Membrane-bound organelles allow for different chemical reactions to occur in isolation, preventing interference between incompatible processes.
4. Evaluate the options: Analyze each option to determine which one aligns with the role of membrane-bound organelles in compartmentalization.
5. Conclude with the correct explanation: Recognize that the primary function of these organelles in compartmentalization is to separate incompatible chemical reactions, ensuring efficient cellular function.
