Halophytes are plants that live in saline soils.The high osmotic potential of the salt solution in the soil creates a very negative water potential.What can halophytes do so that water will flow into the roots?

Question

Quizplus · Accepted Answer

Halophytes can increase the solute concentration in their roots, which means they can accumulate more salts in their roots than in the surrounding soil. This results in a more negative water potential in the roots, which allows water to flow into the roots from the soil. Closing or opening stomata (choices A and B) will not directly affect water uptake from the soil, and pumping ions out of the plant (choice D) would actually make the water potential more negative. Removing mycorrhizal fungi (choice E) would not necessarily help with water uptake if the plant relies on them for nutrient absorption.
