  • Tapetum cells provide nutrition for developing pollen. 
  • Besides this, the tapetum cells deposit sporopollenin substance and help in the formation of the epidermal coat of pollen. 
  • The importance of tapetum can be understood by the fact that if the tapetum degenerates before the formation of pollen grains, the pollen grains remain sterile or abortive.
