Multilamellar membrane structure morphometric analysis. (A) Exemplar multilamellar membrane structure surfaces with membranes labeled. Primary membrane in red. Secondary membrane in yellow. Interior membranes in sage green. (B) Secondary and interior membrane surfaces colored by membrane curvedness; the primary membrane is represented as a transparent gray. (C) Primary surface is colored by membrane curvedness; the secondary and interior membranes are represented as a transparent gray. (D) Primary surface is colored by primary-to-secondary membrane distance; the secondary and interior membrane surfaces are shown in transparent gray. (E) Secondary surface colored by secondary to nearest interior (secondary–interior) membrane distance; the primary and interior membrane surfaces are shown in transparent gray. (F) Secondary and interior membranes surfaces are colored by angle relative to the primary membrane. Primary membrane surface is shown in transparent gray. (G) Secondary and interior membrane surfaces are colored by an angle relative to the growth plane of the cell. Primary membrane surface shown in transparent gray. (H) Primary membrane surface is colored by relative angle to the secondary membrane. Secondary and interior membrane surfaces are shown in transparent gray. (I) Primary membrane surface colored by relative angle to the growth plane of the cell. Secondary and interior membranes are shown in transparent gray.
