Description:

Does John want to be a corn or pea plant? If we were able to put enough plants on Mars, could they produce enough oxygen for us to be able to breathe? Is there a scientific definition of what constitutes a weed? How do purple leaves work? Should I tell my friend she’s been watering a fake plant for seven months? …Hank and John Green have answers!
