Can you help me with some questions about Water Potential and Osmosis?!?

Answer 1

A chef chops vegetables into a bowl of water. Would you expect the vegetable slices to gain or lose water? Explain your answer in terms of water potential.
---It would gain water, but i don't know how to explain the answer.

Imagine that you are an agri-science consultant to a large corporate farm that raises 7000 acres of wheat on a desert land adjoining the Mediterranean Sea. Just before the wheat matures, all the wells used for irrigation water run dry. The farm manager wants to irrigate the fields with water drawn from the Mediterranean. From previous tests, you know that the average solute potential of root tissue taken from the wheat fields is -11.13 bars. You test the seawater and determine its solute potential to be -24.26 bars. What will you advise the farm manager and why?

A marine clam is mistakenly added to a freshwater aquarium. What will happen to the clam and why?

A 1cm diameter, 6 cm long core is removed from a carrot. The resulting hole is filled with corn syrup, and a glass tube is inserted into the hole to make a watertight seal. The carrot is suspended in a cup of pure water. Beginning with the carrot cells adjoining the hole, and going out to the carrot epidermal cells exposed to the water, describe what will happen to the carrot cells. Also, what will happen to the level of liquid in the glass tube and why?

Answer 2

osmosis is diffusion of water
