This paper is concerned with the plant fluid mechanics. The displacement of the dandelion petal movement was measured by the optical displacement detector system. The petal movement speed was determined from the displacement measurements. The surface shape composed of petal cells in the folding and unfolding of dandelion flower head was measured with the color 3D laser scanning microscope. Non-contact measurement of surface roughness on the dandelion petal with laser acquisition of three-dimensional data was conducted over a long period of time. Surface cells showed expansion and contraction through the opening and closing of flower head. Fluid flow in petal cells with the flower head movements was discussed.
