Shaping and promoting a particular tree form is undertaken to establish the plant in a particular situation under certain environmental conditions, to ...
Spider silk structure: crystalline beta-sheets separated by amorphous linkages. Silks have a hierarchical structure. The primary structure is the amino acid sequence of its proteins (), mainly consisting of highly repetitive glycine and alanine blocks, [4] [5] which is why silks are often referred to as a block co-polymer.
The species can be a large shrub or small tree, rarely growing into a large tree 30 metres (98 feet) tall and 40 centimetres (16 inches) in trunk diameter. The trunk is mostly cylindrical or flanged. [ambiguous] The bark is brown, featuring lines of vertical pustules. [4] The leaves are thin with a long pointed tip.
The tree produces spiky green fruits about the size of a golf ball, which turn brown and drop off the tree over an extended period beginning in fall and continuing over the winter.
