Discuss the role of turgor in the crisp lettuce purchased at the grocery store looking much limper by the time it gets home
What will be an ideal response?
ANSWER: At the grocery store, they mist the vegetables with water. The water enters the lettuce cells
generating turgor which keeps the leaves full and crisp. Once you buy the lettuce and the mist
is lost (possibly combined with a ride in a hot trunk), the water leaves the leaf cells reducing
the turgor and causing the lettuce to wilt.
