Current Question (ID: 12549)

Question:

Lenticels are found in

Options:

1. young stems
2. old stems
3. young roots
4. old roots

Solution:

Lenticels are small, raised structures found on the surface of stems and other woody parts of plants that allow for gas exchange between the internal tissues of the plant and the external environment. They are typically found on the outer layer of secondary protective tissue, which is the periderm, and are formed when cork cells in the periderm are ruptured, allowing for the exchange of gases. The periderm is the outer protective tissue that develops in older stems and roots to replace the epidermis, which is the primary protective tissue in young stems and roots. Therefore, options 1, 3, and 4 are incorrect because lenticels are not typically present in these tissues.
