I want to explain something to you about Bees, Pollen and Flowers.

“The basic principles of neurotransmission are well understood. Nervous impulses travel along the nerve fibre until they reach the nerve terminal. The signals cannot cross synapses – the tiny junctions between neurons – so they are converted into a chemical signal. At the terminal, neurotransmitter molecules are stored in spherical structures called vesicles, and the arrival of a nervous impulse causes these to fuse with the terminal membrane and release their contents into the synapse. The transmitter molecules then diffuse across the synapse and bind to receptors on the membrane of the neighbouring cell, causing it to generate its own nervous impulses.”
