Plants can cry for help

Made by: Urbandendro

If plants are damaged they can "cry for help" thru the chemical phone of the root system.

When they are under attack of some pathogen, like some bacteria, plants can send an chemical SOS signal from leafs to the roots. When roots get the SOS signal they will start to produce an special acid which brings to the stage a good bacteria protecting to plant.

It shows us that plants are more organized then we thought earlier - they have abilities which are maybe new for us.
Also it shows that plants can seek for external help.

An interpretation of the article: „Plants Cry For Help“. Livescience.

Arboretum Kórnik (Poland)

Arboretum Kórnik is interesting one - it´s the oldest and biggest in the Poland and it´s quite big (40 hectars) - there is plenty to see.

You can find there over 3300 taxons and it´s history begins in the start of 19th sentury - so there are some trees about 200 years old.

Visiting Japanese Garden in Wroclaw, Poland

Definitely one of the best Japanese style garden I have seen in Europe.
Lot of species, well arranged with big Nishikigoi (Koi) fish.

If you are visiting Wroclaw it is surely worth of visit (Location: Adama Mickiewicza,
51-618 Wrocław).
