Textbook Question
Chapter 39, Problem 5A
You have come up with a brilliant idea to stretch your grocery budget by buying green fruit in bulk and then storing it in a bag that you have blown up like a balloon. As you need fruit, you would take it out of the bag, and it would miraculously ripen. How would this work?
a. The bag would block light from reaching the fruit, so it would not ripen.
b. The bag would keep the fruit cool, so it would not ripen.
c. The high CO2 levels in the bag would prevent ripening.
d. The high O2 levels in the bag would prevent ripening.
