Question

according to the text, what is the primary reason that cell size is limited, leading to a decrease in efficiency as a cell grows larger? * 1 point
the genetic material in the nucleus cannot manage the needs of a much larger cytoplasm.
the production of organelles like mitochondria cannot keep pace with the energy demands of a larger cell.
the plasma membrane becomes too thick as the cell expands, which prevents nutrients from entering.
the surface area - to - volume ratio decreases, impairing the rate of diffusion needed to support the cells interior.

Explanation:

As a cell grows, its volume increases faster than its surface area. The surface area - to - volume ratio is crucial for processes like nutrient and waste exchange. A lower ratio (due to volume outpacing surface area growth) impairs the rate of diffusion (which is related to how nutrients enter and wastes exit). This directly affects the cell's ability to function efficiently as the cell's needs (based on its volume) cannot be met by the surface - related exchange (limited by surface area).

Answer:

The surface area - to - volume ratio decreases, impairing the rate of diffusion needed to support the cell's interior.
