Question

Quizplus · Accepted Answer

Gas exchange in woody stems occurs through lenticels, which are small openings in the bark that allow for exchange of gases between the internal and external environment. Stomata are typically found on leaves and some herbaceous stems, while the waxy cuticle and bundle sheath cells do not play a significant role in gas exchange in woody stems. The cork cambium is involved in secondary growth of the stem and the formation of the outer bark, but is not directly involved in gas exchange.
