Carnivorous plants nepenthes

Evolved plants

All living organisms on the planet have experienced a considerable evolution to reach the present day. In fact, we want to remember that life on earth appeared millions and millions of years ago and, to get to the year 2013, we had to go through an infinity of different events, some of which catastrophic that could easily have wiped out all species. from our planet. And in fact this happened for example for dinosaurs, very famous vertebrates of prehistoric times that did not survive (apparently) a meteorite that hit the Earth. So all those present today as living organisms have had to progressively evolve to survive the acidic atmosphere, aridity, floods, glaciations and volcanic eruptions. This also applies to plants,

Carnivorous plants

An example of the incredible evolution that plants have carried out after having found very difficult living conditions is that of carnivorous plants; the «feeding» mechanism of plants is simple, tested and well functioning, so what led a primordial carnivorous species to stop feeding through roots and move on to small life forms – such as insects and small invertebrates – from which to take nutrients digesting them? Well, clearly the bad conditions of the ground on which they were living, poor in all substances and therefore useless to probe with the roots. They have therefore come to develop an interesting method to attract animals and then trap them, and then usually spray them with acidic liquids to make a sort of breakdown and assimilation take place.

Carnivorous plants nepenthes: Nepenthes

There are various species of carnivorous plants, but not many because it was an extreme and localized evolution. Let’s say that a famous one is the Dionea, with its classic «bite» trap that is truly suggestive. But in this article we want to talk about Nepenthes, a carnivorous plant that exploits the technique of trapping an insect in a bag with closure: it has an elongated cylindrical shape, closed in the lower end and open in the upper; the walls are narrow and covered with a sticky substance that prevents the insect, once inside, from running away. But why should insects, however living beings endowed with a certain intelligence, run away? Simple, because attracted in an «irresistible» way by the perfume emitted by the plant itself in a diabolical way.
