Supplemental Data

Files in this Data Supplement:

• Supplemental Movie 1 - Supplemental movie 1. Tomogram of a chloroplast.
• Supplemental Movie 2 - Supplemental movie 2. A sequence of tomographic sections taken through a granum-stroma assembly. The apparent movement of the stroma and grana thylakoids relative to each other as one goes across the granum body reflects the upward and downward bending of the edges of the granum layers as well as their rotation as they progress along the granum cylinder.
