Biology Translation

Leaves are part of a plant’s shoot system. The xylem tissue in leaves transports —

• the bacteria needed for nitrogen fixation in root nodules

• the wax required to coat the surface of actively growing tissue

•  the water and minerals that are absorbed by the roots

• the oxygen that regulates the rate of carbohydrate production
