Can you please check over thiss for me...Thank youuu...
Note: Elodea is a fresh water plant.
a) Elodea cells normally contain 1% salt and 99% water.
b) Tap water contains 1% salt and 99% water.
c) Salt water contains 6% salt and 94% water.
d) Salt water has a higher concentration of salt than fresh water or Elodea cells.
Answer the following questions using the information above about the cell in salt water:
1) What is the percentage of water outside the cell at the start?- 94
2) What is the percentage of water inside the cell at the start? -99
3) How do the percentages compare? - the percentage of water inside the cell is higher than that of outside the cell
4) When will water move across the cells membrane? -during osmosis?
5) WOuld the cell shape change once it was placed in the tap water? -yes because the cell was trying to equal the concentration of water and salt inside and outside of it...
is all of this correct? if not, can you please correct my answers?!

Seems right, though for #5, you might say whether the shape would grow or shrink.
And Osmosis isn't really a "when", it's a "how". Though I'm guessing that you have the right answer to a poorly worded question.
