Bioimaging of seaweeds. Two-photon laser microscopy image of a rehydrated frond of the red seaweed dulse (Palmaria palmata), showing a single cross-section imaged by both intrinsic fluorescence and a label (4',6-diamidino-2-phenylindole; DAPI) that stains the DNA of the cell nuclei. The excitation wavelength was 780 nm. Scale bar 10 μm.
