Morphological analysis of honeybee antennal cells growing in primary cultures.

abstract：:In lepidoptera the spermatophore is deposited in a bursa copulatrix, which is lined by a cuticle through which solubilized components of the spermatophore must be absorbed by the underlying epithelium. This study follows the route taken by the phosphorus which, with calcium, forms a significant portion of the spermato...

abstract：:1. To be mechanically effective, supporting structures which are helicoidal need to be monodomain, with planar or concentric layers. 2. To achieve this in cholesteric liquid crystalline chemical models, a constraining surface is required. 3. The prediction which logically follows from this is that natural helicoidal s...
