Sporogenous tissues are a group of homogenous cells which occupy the central position of a microsporangium. Microsporangium is a circular structure present in the anther lobes, which further develops into pollen sacs.
How is it formed?
The anther consists of actively dividing cells called archesporial cells. The archesporial cells divide through a periclinal division to give rise to a parietal layer and a sporogenous layer. The cells of the sporogenous layer further divide to give rise to diploid sporogenous cells.
Function
The sporogenous cells undergo meiotic divisions to produce microspore tetrads. Since each sporogenous cell is capable of giving rise to a tetrad, it is known as a pollen or a microspore mother cell. The process of formation of a microspore from the pollen mother cell is known as microsporogenesis.
