This is number 103 of my 'apple' project, in which I followed a gradually desiccating apple for a year. It begins smooth and soft, but just as in the human aging skin, wrinkles become grooves, and finally whole mountain ranges emerge, as on the surface of the earth or other planets. The apple is the fruit of the Malus Domestica from the Rose Family. The fleshy fruit actually consists of three layers, but in the apple these different layers are usually integrated. The core, containing the seeds, is the endocarp. The pulp is formed by both the mesocarp and the exocarp.
