Identify and label A and B in the given image.
Pollen mother cell and octad of pollen
Tetrad of pollen and pollen mother cell
Pollen mother cell and tetrad of pollen
Octad of pollen and tetrad of pollen
Microsporogenesis is the process through which pollen mother cells undergo meiosis division and become pollen tetrads. Microspores, not pollen, make up the pollen tetrad. The pollen tetrads now separate and produce pollen grains as the anther ages and dehydrates. Hence option 3 is the correct answer.
