Halophytes Are Plants That Live in Saline Soils

Multiple Choice

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?

A) They can close their stomata so that less water is lost through transpiration.
B) They can open all their stomata so that transpiration "pulls" more water into the roots.
C) They can increase the solute concentration in their roots creating a water potential that is more negative than the soil.
D) They can pump ions out of the plant creating a water potential in the roots that is more positive than the soil.
E) They can remove the mycorrhizal fungi from their roots decreasing the competition for water.
