A lettuce leaf in the grocery is accidentally submerged in water. Will water exit or enter the lettuce cells? Will the cell swell or crenate? Is tap water hypertonic or hypotonic to the lettuce leaf cells?
Homework Answers
If you put the lecttuce leaf in tap water, water will diffuse in, since tap water is hypotonic to the leaf cells. Tap water is useful for a lot of things, but NOT where distilled water is required. Depending on where you live, tap wate has various minerals in it.
