Ap Biology Water Potential Problems
The original cell from question 1 is placed in a beaker of sugar water with ψ s.
Ap biology water potential problems. Units of water potential pressure potential and solute potential are typically bars megapascals or kilopascals. This quiz is. A cell is in equilibrium with its environment. Since you re waiting for rescue you decide to solve a couple of water potential problems to determine if drinking sea water is a good idea or not.
The cell from question 1 is placed in a beaker of sugar water with ψ s 4 0 bars. To play this quiz please finish editing it. Subjects discussed include osmosis hypertonic solutions isotonic solutions hypotonic solutions and wat. Ap biology ap biology water potential problems name reminders.
The solute potential of the cell s cytoplasm is 0 45mpa. When the cell was first put into the solution it was flaccid. Calculate the solute potential for seawater if you know that the water is 2 c. Your own cells have a 0 15m nacl.
If a cell s ψ p 3 bars and its ψ s 4 5 bars what is the resulting ψ. This quiz is incomplete. The ionization constant of nacl is 2 0. The water potential of the surrounding solution is 0 32mpa.
An introduction to osmolarity and water potential. 9th 12th grade. If there are no units. The majority of dissolved ions in seawater is nacl roughly a 0 5m nacl concentration.
In which direction will the net flow of water be.
