<!-- .vabout -->
This is a sentence of the lesson «The microscopic world: cells, the building blocks of life» of the biology course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (Plant cells, chloroplasts, iodine stain, nucleus), what happens, when and where, as Mova's frames read it from the tree.
