Question

Lenticels are found in

• A. The stem in which secondary growth has taken place
• B. The root where secondary growth has occurred
• C. The roots as well as the stem where secondary growth has occurred
• D. None of these

Answer 1

The correct option is A The stem in which secondary growth has taken place

• A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants.
• It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases. Hence, Lenticels are found in the stem in which secondary growth has taken place.

So, the correct answer is 'The stem in which secondary growth has taken place'.
