Description Notes

Chart has the outline of a cell drawn on it, with a hole where the contents should be.
A second paper (410 x 592 mm) is stuck behind the hole, attached only at the sides, so that the three other sheets can be slid up and down. The three loose sheets are numbered 1-3 (not visible through window).
1. (300 x 804 mm) shows cell contents which are uniformly pink, though the pink has a diagonal split (running down and to the right) across its middle. In the right of the cell are a nucleus, and a dozen green ovals (?chloroplasts).
2. (302 x 778 mm)shows the same nucleus and green ovals, but the rest of the cell contains a red, irregular sac, with a diagonal split towards the bottom.
3. (300 x 750 mm) shows the same nucleus and green ovals, with the rest of the cell occupied by large drops of brown colour, some circular, some tear shaped.
4. shows the same nucleus and green ovals, but the brown drops are all circular now.
Good condition, apart from the back sheet, which is coming off, despite having been re-attached before.
