Which of the following elements is responsible for maintaining turgor in cells?

Options

  1. APotassium
  2. BSodium
  3. CMagnesium
  4. DCalcium

Correct answer

A. Potassium

Step-by-step solution

Potassium is responsible for maintaining turgor in cells. Turgor pressure increases because of a negative water potential due to an influx of potassium ions (K + ). The K + Is pumped in by active transport through channels in guard cell membranes in response to the presence of light.
