Root Hair Cell in 3D using TikZ
A TikZ figure using the beamerposter package. It shows an idealised 3D root hair cell, and its projection onto a 2D rectangular domain. The auxin symplastic pathway is indicated by purple arrows and the longitudinal auxin gradient by a shade in the 2D-domain; influx and efflux permeability arrows, indicating a polarising process, are respectively depicted in orange and light-blue. Switching fluctuation is represented by dark green arrows.
