What is the fundamental biological challenge addressed by maximizing surface area in cells and organisms?

  • A: To increase structural rigidity and support.
  • B: To maintain a constant temperature.
  • C: To facilitate efficient exchange of materials with the environment.
  • D: To reduce overall organism size.

Explanation

The text explicitly states that maximizing metabolic rate requires efficient uptake of energy and raw materials, as well as disposal of waste products. This is achieved by maximizing surface area for exchange, especially when volume increases faster than surface area.
