极性是植物发育的核心，也是其他多细胞生物的核心，因为极性是产生各种特化细胞的驱动力。因此，阐明细胞如何建立极性是理解植物形态发生原理的最基本问题。在单个组织层的平面内协调的细胞极性被特别地称为“平面极性（也称为平面细胞极性）”，其提供了实验上可访问的模型系统。因此，平面极性在各种多细胞生物中被研究。在动物界，果蝇小眼和刚毛的极化排列以及哺乳动物皮肤毛囊的取向都是平面极性的著名例子。
Polarity is at the core of plant development, as well as that of other multicellular organisms since polarization acts as a driving force to generate a variety of specialized cells. Therefore, unraveling how cells establish polarity is the most fundamental issue toward understanding the principles of plant morphogenesis. Cell polarity coordinated within the plane of a single tissue layer is particularly termed “planar polarity (also termed planar cell polarity),” which offers an experimentally accessible model system. Therefore, planar polarity is studied in various multicellular organisms. In the animal kingdom, polarized arrangement of ommatidia and bristles in Drosophila melanogaster and the orientation of hair follicles in mammalian skin are well-known examples of planar polarity.
