Vedclass · Answer

(A) The process described is anther culture,which is a technique used in plant tissue culture to produce haploid plants.In this process,the microspores (pollen grains) inside the mature anther are induced to undergo embryogenesis.Since microspores are formed by meiosis,they are haploid $(n)$.When these microspores develop into embryos and subsequently into plants,the resulting plants retain the haploid chromosome number.Therefore,the plants obtained from the embryos developed within the microsporangia of $Datura$ $innoxia$ are haploid.

When mature anthers of $Datura$ $innoxia$ are cultured in a culture medium supplemented with phytohormones named kinetin,coconut milk,and plum juice,several embryos can be obtained floating inside the microsporangia. These embryos can develop into plants that are:
