The two structures that limit transpiration  are known as

• Guard cells and xylem
• Stomata and guard cells
• xylem and phloem
• stomata and phloem

In which structures would reproduction occur in some non-flowering land plants?

• Roots

• Leaves

• Stems

• Cones

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.
