If pineapples are not C3 nor C4 plants . . . are they CAM plants? It has to
be one of the three I think. CAM plants can temporarily separate their
reactions. They fix their carbon dioxide into malic acid at night. Then
during the day, the carbon dioxide is released from the malic acid and then
fixed via the normal C3 route.
