Answer #1

Answer:(c) gaseous exchange

The lenticels 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.The lenticels help in the gaseous exchange between the atmosphere and the internal tissue of the stem. The lenticels also helps in transpiration called as the lenticular transpiration.Lenticels are a portions of periderm with numerous intercellular spaces and loosely organized cells
