Vedclass · Answer

(B) The tapetum is the innermost layer of the microsporangium wall. During the development of pollen grains,tapetal cells often undergo endomitosis ($DNA$ replication without nuclear division),which leads to the formation of multinucleate cells. This process results in a condition known as endopolyploidy,where the nuclei contain multiple sets of chromosomes. Therefore,the tapetal nuclei are mostly polyploid.
