Fluorescent images of hydrocarbon and polysaccharide repartition on algae colonies. a Colony full of cells (red) with polysaccharides (yellow) and hydrocarbons (green) leaving the colony (×20); b parts of colony tightly packed together (×60), merge of white light with filters 1 and 2; c colony full of cells (red) with dichotomial ramification of polysaccharides (yellow) and hydrocarbons leaving the colony (green) (×100). d Single cell, merge of white light with filters 1 and 2 (×100 and numerically magnified)
