Question 89

By which process does water pass from the soil into a root hair cell?

  1. Active transport
  2. Evaporation from the soil water
  3. Filtering through the cell wall under pressure
  4. Osmosis across the cell membraneBonne réponse

Explication

Soil water is a more dilute solution than the contents of the root hair cell, so osmosis carries water across the membrane down that difference without the cell spending anything to make it happen. Active transport is the mechanism that handles the ions rather than the water, and invoking it here adds an energy cost to a movement that occurs on its own.
