Q. What is microsprongium ?​

Answer 1

Answer:

Microsporangia are sporangia that produce microspores and give rise to male gametes. Microsporangia occur in all plants that have heterosporic life cycles, such as spike mosses. In gymnosperms and angiosperm anthers, the microsporangia produce the microsporocytes, the microspore mother cells, which then produce four microspores through the process of meiosis. In the microsporocyte of Arabidopsis thaliana, meiosisdepends on the expression of genes that facilitate DNA repair and homologous recombination.[1] The microspores divide by mitosis to produce pollengrains.
