Water Potential
Additional Problems
During a drought plants close stoma bya. moving sodium (Na+) ions out of guard cellsb. adding water to gaurd cellsc. increasing the turgor of guard cellsd. removing water from guard cellse. moving potassium (K+) ions into guard cells
You are moving from Georgia to Southern Florida, and decide to take your favorite plant, except that the humidity is higher. Under these conditions you should expect thata. the plant requires more wateringb. the plant requires less nutrientsc. the plant requires more nutrientsd. the plant requires less wateringe. the plant will grow more slowly
Which of the following is evidence against the root pressure hypothesis?a. water molecules held together by cohesionb. water entering root cells by osmosisc. water pressure is higher in the roots than at the top of a 6m tall treed. droplets of water exiting stomatae. plants can stay alive after roots have been injured
Most of the water within xylem vessels moves towards the top of a tree as a result ofa. active transport of ions into the tracheidsb. osmosis in the rootc. the force of root pressured. evaporation of water through stomatae. atmospheric pressure on roots
How do terrestrial plants regulate the amount of water they transpire? What negative consequences might result from prolonged reduction of the amount of water transpired?
Explain how plants without a heart, can pump water up sometimes hundreds of feet above ground. Base your explanation in the characteristics of water molecules and water potentials.
Is water mostly pushed up the tree from the roots or pulled up the tree from the leaves? Briefly explain
Describe how water within xylem vessels moves toward the top of a tree.
