Female reproductive organs
It is winter and there are no fresh deciduous leaves to print on the trees, so I turned to fruit. Image capture was a straightforward high-resolution scan. I chose the apple because it's gynoecium [the female reproductive organs] are a five-pointed star or pentagram. This was of particular interest following the hexagon experiments as the points of the star define another geometric figure, the pentagon. Euclid describes how to construct a pentagon in Book IV, Proposition 11. It is interesting to note how the cross-section of the apple is almost perfectly circular.
