Vedclass · Answer

(A) The sporogenous tissue consists of microspore mother cells $(MMC)$. Each $MMC$ undergoes meiosis to form a microspore tetrad. Thus,the Assertion is correct.In dicots,cytokinesis is simultaneous,leading to tetrahedral tetrads,which are the most common type. In monocots,cytokinesis is successive,leading to isobilateral tetrads. Since simultaneous cytokinesis is the most common process in angiosperms,the Reason is also correct and explains why the potential for forming tetrads is widespread in sporogenous tissue.

$A$: Each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad.
$R$: The most abundant type of microspore tetrad is the product of simultaneous cytokinesis.
