Cheeseburger Chemistry: Tomatoes -- Chemistry Now (Encore)


Thinking about a Fourth of July celebration? Don't forget the cheeseburgers...and the tomatoes. This video, one of our six-part "Cheeseburger Chemistry" series, examines the role of the plant hormone ethylene, or C2H4, in ripening tomatoes (and other fruits); lycopene's connection to tomatoes' red color; and how ethylene gas diffuses.

Happy Fourth!

Original air date: June 23, 2011.
