Cell-cell adhesion is a fundamental feature of multicellular organisms. To ensure multicellular integrity, adhesion needs to be tightly controlled and maintained. In plants, cell-cell adhesion remains poorly understood. Here, we argue that to be able to understand how cell-cell adhesion works in plants, we need to understand and quantitatively measure the mechanics behind it. We first introduce cell-cell adhesion in the context of multicellularity, briefly explain the notions of adhesion strength, work and energy and present the current knowledge concerning the mechanisms of cell-cell adhesion in plants. Because still relatively little is known in plants, we then turn to animals, but also algae, bacteria, yeast and fungi, and examine how adhesion works and how it can be quantitatively measured in these systems. From this, we explore how the mechanics of cell adhesion could be quantitatively characterised in plants, opening future perspectives for understanding plant multicellularity.
细胞间粘附是多细胞生物的一个基本特征。为确保多细胞的完整性，粘附需要受到严格控制和维持。在植物中，人们对细胞间粘附的了解仍然很少。在这里，我们认为，要了解细胞间粘附在植物中是如何起作用的，我们需要理解并定量测量其背后的力学原理。我们首先在多细胞性的背景下介绍细胞间粘附，简要解释粘附强度、功和能量的概念，并阐述目前关于植物细胞间粘附机制的知识。由于在植物方面仍所知相对较少，我们接着转向动物，还有藻类、细菌、酵母和真菌，研究这些系统中粘附是如何起作用的以及如何进行定量测量。由此，我们探索如何在植物中对细胞粘附的力学原理进行定量表征，为理解植物多细胞性开启未来的研究前景。
