Pollen tube stained for mitochondria (MitoTracker Green, green) and lysosomes (Lysotracker Red, red). Watch the pollen tube extend from the crack in the pollen grain (visualized by its autofluorescence). Mitochondria don't quite advance to the very tip of the pollen tube but stop a few microns before the tip. Rendering of the data set was performed in arivis Vision4D®. Sample: courtesy of R. Whan, UNSW, Sydney, Australia. --- For more information on ZEISS Lattice Lightsheet 7 and further applica
