Details of the ultrastructure of control cells of Zygnema sp. E. a Long and narrow chloroplast lobes covered by large medium electron-dense compartments (asterisks) and electron-dense particles (arrow); b cortical area with electron-dense particles and vacuoles; c central area of the cell with nucleus and part of the nucleolus (arrow), vacuoles in the cell cortex; d chloroplast detail with pyrenoid, mitochondria and nucleus; e detail with Golgi bodies, mitochondria and chloroplast lobes.
