☆The tapetum is a layer of

nutritive cells found within the sporangium,particularly within the anther of flowering plants.

─━━━━━━━━━━━━──━━━━

✧Tapetum is important for the

development of pollen grains. The cells

are usually bigger and have more than one nucleus per cell. As the sporogenous cells undergo mitosis, the nuclei of tapetal cells also divide large nuclear constitution of thetapetum helps in providing nutrients and regulatory molecules to the forming pollen grains.

The tapetum is a specialised layer of nutritive cells found within the anther, of flowering plants, where it is located between the sporangenous tissue and the anther wall. Tapetum is important for the nutrition and development of pollen grains, as well as a source of precursors for the pollen coat.The cells are usually bigger and normally have more than one nucleus per cell. As the sporogenous cells undergo mitosis, the nuclei of tapetal cells also divide. Sometimes, this mitosis is not normal due to which many cells of mature tapetum become multinucleate. Sometimes polyploidy and polyteny can also be seen. The unusually large nuclear constitution of the tapetum helps it in providing nutrients and regulatory molecules to the forming pollen grains. The following processes are responsible for this:

  • Endomitosis
  • Normal mitosis not followed by cytokinesis
  • Formation of restitution nuclei
  • Endoreduplication
