mother cell उदाहरण वाक्य
उदाहरण वाक्य
- Reproduction occurs by segregative cell division, where the multinucleate mother cell makes daughter cells, and individual rhizoids form new bubbles, which become separate from the mother cell.
- This results in a mother cell retaining the memory of the previous encounter over multiple generations, while the new daughter cells are still responsive to mating cues.
- In a process called "'microsporogenesis "', four haploid microspores are produced from each diploid sporogenous cell ( microsporocyte, pollen mother cell or meiocyte ), after meiotic division.
- It involves an unusual process in which two daughter cells are produced inside a mother cell, which is then consumed by the offspring prior to their separation.
- An experienced mother cell ( one that has divided at least once ) will switch mating type every cell division cycle because of the " HO " allele.
- When the pollen mother cells ( PMCs ) go through the last premeiotic mitosis, the tapetal cells have one diploid nucleus which divides while the cell remains undivided.
- In multi-celled organisms this mechanism raises two requirements : first, the mother cell must be polarized; second, the mitotic spindle must be aligned with the axis of polarity.
- Spore mother cells in the microsporangia divide by meiosis to form haploid microspores that develop further by two mitotic divisions into immature male gametophytes ( pollen grains ).
- The daughter cells obtained from this budding, however, are not conditioned against mating, unlike the mother : the WHI3 aggregates have been shown to localize within the mother cell.
- Later the zygote will give rise to the embryo of the seed, and the endosperm mother cell will give rise to endosperm, a nutritive tissue used by the embryo.
