• Unlike simple plants, such as mosses, higher plants produce 2 kinds of spores. What are the 2 types of spores produced by higher plants and how do they differ from each other?

• Answer:

  Megaspores, microspores In angiosperm and gymnosperm plant's ovules (megasporangia) produce megaspores that mature into the female gametophytes inside the flower ovary or under the cone scale. The male sporangium produces the microspores. Each microspore is a single cell that grows into a mature gametophyte (multicelled pollen grain) with a reduced antheridium to generate sperm nuclei. These are in male cones in gymnosperm or in anthers in angiosperm.
