Organic solvents: Acetone, benzene, ethanol, ether, chloroform and phenol, are generally regarded as toxic to organisms. To ensure the availability of pollen throughout the year without using nurseries or artificial climate growth rooms. Insects visit flowers for nectar, edible pollen grains or shelter. Cross-Pollination or Allogamy is the transference of pollen grains from the anther of a flower of one plant to the stigma of a flower of another plant of the same species. Some Mesozoic beetles, already adapted to a diet of spores from primitive plants, apparently became pollen eaters, capable of effecting chance pollination with grains accidentally spared. Snails are select pollinators on stormy days when honey bees are not dynamic. "@type": "Answer", Pollen grains are rough and sticky and often with spinous outgrowths.
