When and where does reduction division take place in the life cycle of a liverwort, a moss, a fern, a gymnosperm and an angiosperm?

Explanation

Reductional division in the life cycle of gymnosperm occurs in the megasporongium in femal and microsporongium in male. In megasporongium reductional division occur at the time of formation of megaspores. In microsporangium meiosis occur when they are present in the form of sori on microsporophylls.
