THERE ARE NO IMMORTAL NORMAL CELLS. "As a result of our demonstration that normal cells are mortal, the focus of attention in the field of aging began to be directed to the cell itself, and the dogma of fifty years duration began to die a slow death." http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn

FUTILE SEARCH. "The failure of grafted normal cells to replicate indefinitely in vivo means that, given the "perfect" conditions of nutrition and environment that an isologous animal represents, transplanted normal cells are still incapable of immortality. This leads to the further conclusion that a search for perfect in vitro conditions in which normal cells might reveal immortality is futile." http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn

THE AVERAGE JOHN. "The typical pollinator of a sexually deceptive orchid is a male insect of a species that is polygynous, monandrous, haplodiploid, and solitary rather than social. Insect behaviours involved in the pollination of sexually deceptive orchids include pre-copulatory gripping of flowers, brief entrapment, mating, and very rarely, ejaculation." https://lnkd.in/dp7q3mK View in LinkedIn

INSECT POLLINATORS. "I was led to attend to the cross-fertilisation of flowers by the aid of insects, from having come to the conclusion in my speculations on the origin of species, that crossing played an important part in keeping specific forms constant." (Charles Darwin, 1862). https://lnkd.in/dSQjj95 View in LinkedIn

SEXUAL RESPONSE. "Among the oddities of pollination, various forms of sexual deception are perhaps the most unusual. The flowers of some species produce sex pheromone-like odors that attract particular species of male insects. The interaction is often species specific, at least locally. In the case of Orchid galileae, its halictid bee pollinators seem to be attracted by deceptive floral fragrances, but copulatory behavior during pollinating visits does not occur." https://lnkd.in/db9X2SK View in LinkedIn

ORCHID FUNGUS MIMESIS. "The floral parts of these flowers simulate fungi and emit mushroom-like odors. Fungus gnats are misled by a suite of cues so that they lay their eggs in the flower and pollinate it in the process. The flowers are inedible so the larvae eventually starve to death." https://lnkd.in/db9X2SK View in LinkedIn

OVER-SIMPLIFIED. "However, the plant-pollinator relationship is somewhat more complex because brood-site deception is not the only means of pollinator attraction. The flowers also produce nectar which is consumed by male and female flies, both of which pollinate the orchid." https://lnkd.in/db9X2SK View in LinkedIn
