0214 A Study on the Surface Cells as the Plant Hydrodynamics : Observation of Dandelion Petal in a State of Absorbing Water

Abstract

This paper describes the results of microscopic observations on the petal surface of dandelion by the 3D laser scanning microscope. The change in surface shape of the cells with the movement in folding and unfolding of dandelion flower head was recorded by the analysis based on the measurements of surface roughness. Time variation of the surface roughness in live petal cells was revealed. The relation between the plant cell growth and the water flow in the plant cell was discussed from the viewpoint of fluid mechanics.
