Arrangement of cells in vegetable tissues

Abstract

The authors study the arrangement of cells in undifferentiated vegetable tissues of five different species. The distribution of the number of sides, the average area (an), perimeter (pn) and side length (ln) of n-sided cells are determined as well as the correlation between the number of sides of a cell and of its neighbours. The results show that vegetable cellular nets obey Aboav-Weaire's law. They also discuss Lewis' law and a possible relation between (pn) and n. The analysis of these structures provides a different example of random cellular structures and helps to show general aspects of the ideal one.
