Exercise 1 - solution

Layers, outside to inside: outer skin (exocarp), pulp (mesocarp), mucilage (pectin layer), parchment (hull/endocarp), silver skin (testa), bean (endosperm).

(a) Dry method: the whole fruit dries, so skin, pulp, mucilage and parchment are all still on the seed (silver skin is under the parchment, also still there).
(b) Black honey: skin and pulp are removed but all the mucilage stays, so mucilage, parchment and silver skin remain around the bean.
