A plant cell must build a new wall between its daughter cells. Where does the material come from?

1. A plant cell is boxed in by a rigid wall, so it cannot pinch inward. 2. During interphase the Golgi stockpiles enzymes, structural proteins and glucose. 3. These are packed into vesicles that travel on microtubules to the old metaphase plate. 4. There they fuse into a phragmoplast and then a cell plate, which grows outward to the walls. 5. An actin ring would only work in a cell without a wall to push against. _Source: OpenStax Biology 1e (CC BY 4.0), Chs 10 and 11, section 10.2 The Cell Cycle_
