In a hypertonic solution, the water moves
it moves back and forth continuously
it does not move
inside the cell
outside the cell
In a hypotonic solution, the water moves
outside the cell
into the cell
it does not move
continuously moves
In an isotonic solution, the water moves
out of the cell
into the cell
in and out at the same rate
it does not move
What is turgor pressure and how is it created?
It is created when the protein gate is too small.
It holds plant cells together and is created by water entering the cell.
The water leaves the cell and creates pressure.
It only happens in prokaryotes when it moves.
