Plants of the olygotrophic swamps
Слайд 51. Lack of nutrition
Olygotrophic swamps are water reservoirs which are poor
with organic matter, actually with nitrogen compounds.
Слайд 6
Due to such severe conditions, plants of swamps, or OXYLOPHYTES, have
some special characteristics.
Here are some of them.
Here are some of them.
Слайд 10
….have some special cells, which produce fellem.
…имеют специальные клетки, производящие пробку.
Слайд 12
These cells, or FELLOGENE cells, also are A BORDER between a
stem and some outer tissues, which are to be separated from the stem.
Эти клетки, или клетки ФЕЛЛОГЕНА, также находятся на ГРАНИЦЕ стебля и других тканей коры, которые затем отваливаются от стебля.
Эти клетки, или клетки ФЕЛЛОГЕНА, также находятся на ГРАНИЦЕ стебля и других тканей коры, которые затем отваливаются от стебля.
Слайд 13
So the parts of tissues located ABOVE the FELLOGENE separate from
the stem. It leads to decrease in nutrition losses during growing season.
Слайд 142. Low temperature
These swamps are regions with relatively low-temperatured soil.
Олиготрофные
болота – зоны со сравнительно низкой температурой почвы.
Слайд 15
It influences badly on roots, because absorption of water is complicated.
Это
плохо влияет на корни, т.к. всасывание воды [при низких температурах] затруднено.
Слайд 16
On the other side, the sun rays reach plants very fast,
which makes all the aerial runners warmer.
Слайд 17
As a result, subterranean organs of OXYLOPHYTES are subjected to cold,
but aerial ones are overheated.
Слайд 18
But leaves of Chamaedaphne (мирт) also have double layers of photosynthetic
tissue to accumulate more sun rays.
Слайд 19Due to this fact, the leaves of Andromeda (подбел многолистный) are
placed at an angle to the horizon.
Слайд 213. Water excess
Finally, the soil of olygotrophic swamps is very
MOISTENED, so athmosphere OXYGEN can not penetrate through it.
Слайд 23
And OXYLOPHYTES have some adaptations for breath:
They possess special tissue
termed AERENCHIMA. It contains cells and plenty of air cameras!
Слайд 27
There are much more ecological factors, which influence on the OXYLOPHYTES;
these factors caused evolutionary adaptations in plants.
Слайд 28
So the plants of olygotrofic swamps are adapted to high and
low temperatures, lack of nutrients and oxygen.
