✔Develpoment of two types of spores is known as heterospory and the plants are known as heterosporous.
✔Megaspores produce female gametophyte while microspore produce male gametophyte.
✔In seed bearing plants the gametophytes produced by megaspores and microspores are very small and never released from the spores.
✔This retention and germination of the megaspore within the megasporangium ensures proper development of the zygote.
✴Thus heterospory is considered an important step in evolution as it is a precursor to the seed habit.
