Haryana PMTHaryana PMT 2007
Solution:
Lenticels are some loosely arranged areas in the periderm. Due to more activity of certain portions of phellogen, the phellem cells are cut off very rapidly and hence, these cells are loosely arranged with much intercellular spaces. These loosely arranged cells are called complementary cells and loosely arranged areas in the periderm are called lenticels.
