Vedclass · Answer

(B) In a typical flower, the hierarchy of structures is as follows:$1$. $A$ flower contains multiple stamens (microsporophylls).$2$. Each stamen (anther) typically contains four microsporangia (pollen sacs).$3$. Each microsporangium contains many microspore mother cells (MMCs).$4$. Each $MMC$ undergoes meiosis to produce four microspores (pollen grains).Therefore, the descending order of quantity is: $Stamen  >  Microsporangium  >  Microspore Mother Cell  >  Microspore$.
