Microscope Zeiss Universal, camera Olympus C7070WZ. DOF images.
Sampling date 04/2007. Scale bars indicate 100 µm.
Chloroplasts with stellate shape in cross-section. The inset shows the delicate surface texture of cell wall surface in high resolution (Planapochromat 63/1.4). The usually seen longitudinal stripes are not yet developed.
First cell developed from a cystozygote. In species with girdle bands, first cells are characterized by the fact that they are without them!
