Solution:
Tapetum is the innermost layer of a developing anther. The tapetal nudei may divide once or more and sometimes these divisions are accompanied by nudear fusions resulting in large polyploid nudei which may divide again. The tapetal layer is of great physiological significance since all the food material entering into the sporogenous tissue diffuse through this layer. At maturity these cells degenerate and provide nourishment to developing microspores or pollens inside.
