WebThe sporangia of angiosperm plants are found in two places within the flower depending, on whether they lead to a female or male gametophyte. The sporangium in the anther (where the male gametophyte will be formed) is called the microsporangium . The sporangium in the ovary (where the female gametophyte will be formed) is called the megasporangium. WebThe angiosperm female gametophyte is critical to the reproductive process.
