Question

what is the function of tapetum during microsporogenesis?

Answer 1

The important functions of tapetum during the microsporogenesis are;

• The primary function of tapetum is the nourishment of pollen grains during microsporogenesis.
• It also plays an important role during the formation of pollen wall (exine).
• The amoeboid tapetum produces the callase enzyme which degrades the callose wall of the microspore tetrad.Thereby separating the pollen tetrad into individual pollen grains.
• The protein responsible for recognising the compatibility of the pistil is also contributed by the tapetum to the pollen wall.
• Some of the specific proteins of the pollen wall produced by the tapetum causes pollen allergy.
