1. Microspore

   Microspores are land plant spores that develop into male gametophytes, whereas megaspores develop into female gametophytes. The male gametophyte gives rise to sperm cells, which are used for fertilization of an egg cell to form a zygote. Megaspores are structures that are part of the alternation of generations in many seedless vascular cryptogams, all gymnosperms and all angiosperms. Plants with heterosporous life cycles using microspores and megaspores arose independently in several plant groups during the Devonian period. Microspores are haploid, and are produced from diploid microsporocytes by meiosis.

1. microspore

   A microspore is a type of spore in plants and algae that is smaller than the megaspore. It is involved in the reproduction process by developing into a male gametophyte or pollen grain. During the process of sexual reproduction, microspores are produced by the male parent and are carried to the female parent to fertilize the megaspores.
