Question

What is the diffrence between Microsporophyll and Megasporophyll???

Answer 1

Microsporophyll bears microsporangia. Microsporangium bears pollen grains(microspores). The pollen grains are not retained in microsporangia. They are always shed.Male gametophyte is formed near female gametophyte. In angiosperms it is modified into stamens.

Megasporophyll contains megasporangia. Megasporangia contains one functional megaspore.In seed plants megaspores are retained. In seed plants female gametophyte formed in megasporangia fertilization and embryo forms there. In angiosperms it is rolled to form carpels.
