Many plants, including American oak (Quercus sp.), aspen (Pop- ulus sp.), and kudzu (Pueraria lobata) emit gaseous five-car- bon molecules ... Thus, C 4 plants can use water and nitrogen more efficiently than C 3 plants can. On the other hand, the additional energy cost of the concen- trating mechanism (see Chapter 8) makes C...
