Praxis 5005 Practice Question
Which of the following parts of a plant cell is most important in providing structural support and protection?
Correct Answer: C
Rationale: The cell wall is crucial for providing structural support and protection in plant cells. It maintains cell shape and prevents excessive water intake, which is vital for plant integrity.
Mitochondria (A) are primarily involved in energy production, not structural support. The plasma membrane (B) offers some protection and regulates transport but lacks the rigidity needed for structural support. The nucleus (D) serves as the control center for genetic information and cell function, but does not contribute to the cell's structural integrity. Thus, the cell wall is uniquely suited for its protective and supportive roles.
