Fig. 6 in In situ experiments on the effect of low pH on the ultrastructure of the seagrasses Cymodocea nodosa and Posidonia oceanica Abstract

Fig. 6: A-E. TEM micrographs of young epidermal cells of C. nodosa after three weeks transfer at S1 area. A. Group of epidermal cells that appear empty, with most of the cell elements disorganized and distorted. B. Higher magnification of a nucleus with condensed masses of chromatin which covered most of the nucleoplasm. The nuclear membrane appears loose and discontinuous. C. Cytoplasmic area showing dictyosomes with few cisternae and numerous swollen fragments of rough ER (RER) D. Fragmented ER membranes traversing the cortical cytoplasm. E. Disorganized chloroplasts with large starch grains surrounded by a system of electron-dense elongated or round plastoglobuli. Mitochondria with a few broken and sometimes dilated cristae are also observed. Scale bars = 1 μm (A), 0.5μm (B, C, E) and 0.2μm (D).
