  • pistils in the flower
  • root hairs in the epidermis
  • xylem in the stem
2. Which three processes are indicated by the arrows in the diagram below?

  • NH3 and CO2
  • H2O and O2
  • H2O and CO2
8. In trees, shrubs and other woody plants, the exchange of CO2 and O2 with the environment may occur through structures known as
  • spiracles
  • anthers
  • lenticels
  • rhizoids
9. Small hairs on the legs of certain insects have the ability to detect chemicals. These hairs function as
