Thermal images are photographs of the heat emitted by an object. Researchers have used thermal imaging of plants to isolate mutants that overproduce abscisic acid. Suggest a reason why they are warmer...

to isolate mutants that overproduce abscisic acid. Suggest

a reason why they are warmer than wild-type plants under

conditions that are normally nonstressful.
