Answer Details
In woody stems, gaseous exchange takes place through the lenticels. Lenticels are small pores or openings on the bark of woody stems that allow for gas exchange between the inner tissues of the stem and the surrounding environment. Unlike stomata, which are found on leaves and are used for gas exchange in herbaceous plants, lenticels are specifically adapted for gas exchange in woody stems. They allow for the exchange of gases like oxygen, carbon dioxide, and water vapor, which are important for the survival of the plant. Lenticels are particularly important during periods of active growth and development, as well as in response to environmental stresses such as flooding, drought, and extreme temperatures.
