1. These sets of sporogenous cells eventually develop into diploid microspore mother cells . 2. Duplicate a human and see how differently it develops from its mother cell . 3. Mother cells give rise to progeny buds by mitotic divisions, but undergo replicative rejuvenation.4. After another nuclear division, each sporoblast mother cell turns into a chain of four sporoblasts. 5. Thus, a single growth step may result in 4 or 8 daughter cells per mother cell . 6. These microspore mother cells , also called microsporocytes, then undergo meiosis and become four microspore haploid cells. 7. This meristemoid then divides asymmetrically one to three times before differentiating into a guard mother cell . 8. The guard mother cell then makes one symmetrical division, which forms a pair of guard cells. 9. Each companion cell is derived from the same mother cell as its associated sieve tube member. 10. Daughter cells are spawned by mother cells .
