In a flowering plant, archesporium gives rise to : -In a young anther, a group of hypodermal cells in each corner becomes the archesporium.
Each archesporial cell divides periclinally into an outer primary parietal cell and an inner primary sporogenous cell.
The primary parietal cell divides further to form the wall layers of the microsporangium: endothecium, middle layers and tapetum.
The primary sporogenous cell gives rise to the sporogenous tissue, whose cells become microspore mother cells; these form pollen grains by meiosis.
So the archesporium gives rise to both the wall and the sporogenous cells.
