![Fig. 3. Cell-specific silicon concentrations in selected individual sedges acquired using CryoSEM-EDX. For each species, a schematic diagram is shown of the different anatomical areas, together with a qualitative representation of the distributions of silicon (green) and carbon (purple) (Si-C), and a heatmap of silicon concentration, [Si]. (A) Machaerina junceae, (B, C, E) Cyathochaeta equitans, (D) Schoenus rigens, and (F) Mesomelaena tetragona. Scale bars are 100 µm in (A–D, F) and 25 µm in (E).](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:7i6qyjt427sjvjwpngi73id7/bafkreidcvq54boplj4zjdzve5euzvh4uyd3eednwurh5r64jtuqb37isym)
