What causes polarity in an embryo?
Establishment of polarity in embryos requires displacement of various cell fate determinants. This redistribution is often mediated by a cytoplasmic flow, a directional cytoplasmic movement dependent on actomyosin cytoskeleton. The mechanism of cytoplasmic flow was examined in detail in C. elegans embryos. How is polarity important in embryonic development in plants? Cell polarity is one…
