If a cell has a water potential of -200kPa, what must the water potential of the external solution be if it is hypotonic !
explain question and answer ! thx

A hypotonic solution is where the water diffuses out of the cell down a water potential gradient because the surrounding solution has a lower water potential so for the solution to be hypotonic the surrounding solution will have a water potential of <-200kPa. If it was Isotonic it would have a water potential of -200kPa and if it was hypertonic it would has a water potential of >-200kPa :) Hope this helps

Pure water has a water potential, by definition , of Zero, and is hypotonic to a water potential of 200kPa
Any solution with a value less negative than -200kPa.

The water in the cell are not hydrogenous
