Reconstruction 3D d'une microalgue du groupe des diatomées

3D reconstruction of a microalgae in the diatom group, phaeodactylum tricornutum. The cellular complexity of diatoms, a major group of marine phytoplankton, is only now becoming apparent. Studying series of cross-sections produced using electron microscopy reveals the three-dimensional organisation of organelles inside their cells. The scientists produced a 3D reconstruction of diatom cells, showing their internal ultrastructure and compartments. This model also enabled them to understand how these organisms organised the intetrnal structure of their chloroplast to optimise photosynthesis.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
