(a-f) Growth process of calcite seeds. Images are taken with a CLSM (confocal laser scanning microscope). Images are taken (a) 1 min before the growth process started, and (b) 1 min (c) 3 min (d) 6 min, (e) 11 min and (f) 14 min after the growth process started. (g) Finished crystal. The original fluorescent calcite seed (originated from an abiotic process) had a fluorescent dye incorporated and was visualized with CLSM. The scale-bar is 10 μm.
