1) In an experiment where a cell containing a 3% sucrose solution is placed into a beaker containing a 7% sucrose solution and the cell's membrane is permeable to water but not permeable to sucrose, the water will go into the cell. Water follows its concentration gradient meaning that it will go from a higher concentration to a lower one. It does this to make the concentration of molecules equal inside and outside of the cell. Sucrose will not go through the cell wall because the parameters of the experiment show the cell was not permeable to sucrose. Simply stated the cell wall would not allow sucrose to pass through it

2) Each turn of the Calvin cycle does not produce one molecule of glucose. So, the statement is false. Every three turns of the Calvin cycle produces one molecule of glucose. RuBP is a 5 carbon chain that bonds 3CO2. Now you have a 6 carbon molecule. This 6 carbon molecule is split in half and makes 2-3 carbon molecules. One of the 3 carbon molecules goes toward making glucose and the other one goes to regenerate the RuBP. This must happen 3 times in order to make one molecule of glucose.
