Figure 3. The ultrastructural examination of morphological changes and lipid droplet formation in Symbiodinium after A. pulchella under nitrogen deprivation.

Figure 3

Transmission electron micrographs of A. pulchella in normal (A–B) and nitrogen-deprivation media (5 days: C–D; 30 days: E–F). Insets in A, C and E were magnified as B, D and F, respectively. Scale bars represent 5 μm and 2 μm. Abbreviations: LD, lipid droplet; Ch, chloroplast; Pyr, pyrenoids; N, nucleolus; acc: accumulation body, Host LD: host lipid droplet.
