Roots adaptations for gas exchange

WebApr 9, 2024 · Plants form these structures when roots cannot be respired normally because oxygen is insufficient for their roots. Root respiration is made possible by an abundance of breathing pores or openings called lenticels that allow gas exchange. Roots are modified in order to allow their roots to breathe. WebOther adaptations of flood-tolerant species include formation of hypertrophied lenticels on submerged portions of stems and on roots as well as formation of aerenchyma tissue with large intercellular spaces through which O2 is easily transported (see Chapter 5 of Kozlowski and Pallardy, 1997 ).
