Spider silk spinning field, the spinneret apparatus of an adult "Araneus diadematus" (garden cross spider) consists of the glands shown below. Similar multiple gland architecture exists in the black widow spider. In order to artificially synthesise spider silk into fibres, there are two broad areas that must be covered. These are synthesis of the feedstock (the unspun silk dope in spiders), and synthesis of the spinning conditions (the funnel, valve, tapering duct, and spigot). There have been a number of different approaches. The molecular structure of unspun silk is both complex and extremely long. Though this endows the silk fibres with their
Kyoto Botanical Garden Trees; European Style Garden; Flower Bed; Hydrangea Garden; Japanese Iris Garden; Japanese Native Plants; Lotus Pond; Nakaragi-no-mori Pond (trees native to the Yamashiro Basin); Peony Garden; Perennial and Useful Plants Garden; Sunken Garden; and the Uma Grove. The garden also contains a very substantial conservatory complex (4,694 m²) containing about 25,000 specimens representing 4,500 species. It is a set of rooms shaped to resemble the nearby Kinkaku-ji Temple and Kyoto's northern mountains, built of glass with iron frames, and opened in 1992. It currently contains the following areas: Ananas Room; Aquatic and Carnivorous Plants; Bromeliads Room; Desert and Savanna Plants
