- Pollen grains are produced from microspore mother cells (also known as microsporocytes) through meiotic division. - Each microspore mother cell undergoes meiosis, resulting in the formation of four microspores. 2. Determine the Relationship Between Meiotic Divisions and Pollen Grains: - From one...
