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. WebDuring plant sexual reproduction, F-actin recorded part in the elongation of the pollen tubular and the movement of sperm cells along with it.
