  How morphogenesis depends on cell properties is an active direction of
research. Here, we focus on mechanical models of growing plant tissues, where
microscopic (sub)cellular structure is taken into account. In order to
establish links between microscopic and macroscopic tissue properties, we
perform a multiscale analysis of a model of growing plant tissue with
subcellular resolution. We use homogenization to rigorously derive the
corresponding macroscopic tissue scale model. Tissue scale mechanical
properties are computed from microscopic structural and material properties,
taking into account deformation by the growth field. We then consider case
studies and numerically compare the detailed microscopic model and the
tissue-scale model, both implemented using finite element method. We find that
the macroscopic model can be used to efficiently make predictions about several
configurations of interest. Our work will help making links between microscopic
measurements and macroscopic observations in growing tissues.
