Plant cells inherit knowledge of where's up and where's down from mother cell

For plants, which grow roots into the soil and flowers above ground, getting this polarization wrong would cause a whole host of problems. In plants, polarization of the entire organism depends on every single cell being polarized. Cell division, however, disrupts polarization. How polarity is reestablished was previously unknown.
