Amazing Unknown Facts About Tree's!

Interestingly These Facts Are True And Proven

 

We Bring You 7 Such Facts Which May Change Your The Way You Think About Tree's

 

 

7)They’re Just As Stressed As We Are


Trees are very sensitive to their environments. The disruption of an ecosystem—whether caused by man or nature—can greatly stress a tree. In urban environments, poor soil quality, overcrowded tree planters, and competition for water between different plants are the most common stress to trees. If not treated, such stress can inhibit a tree’s growth or photosynthesis cycle. So, the next time you see a stressed tree, help it out! Keep your soil nutrient-rich and give your trees plenty of space to breath.

6)Single tree produce 2,721 kilograms (5,998.78 pounds) of oxygen per year 
 

A single 30-meter-tall mature tree can absorb as much as 22.7 kilograms (50 pounds) of carbon dioxide in a year, which over it’s lifetime is approximately the
same amount as would be produced by an average car being driven 41,500 kilometers (25,787 miles). The same tree could also produce 2,721 kilograms (5,998.78 pounds) of oxygen in a year, which is enough to support at least two people. According to the University of Melbourne, because trees grow faster the older they get, their capacity for photosynthesis and carbon sequestration increases as they age.


5)A single tree supports 284 species of insects


You probably knew that trees were good for wildlife but did you know just how good? For example, the common English Oak (Quercus robur) can support hundreds of different species, including 284 species of insect and 324 taxa (species, sub-species, and varieties) of lichens living directly on the tree. These in turn provide food for numerous birds and small mammals. The acorns of oak trees (which don’t usually appear until the tree is around 40 years old) are food for dozens of species, including wild boar (and now more commonly pigs), jays, pigeons, pheasants, ducks, squirrels, mice, badgers, and deer.

4)A single tree has cooling effect of 10 AC




Most people know that trees near buildings can raise property prices by an average of 14 percent in the U.K. and as much as up to 37 percent in the U.S. But trees can also have an impact on the energy used for heating and cooling a building, reducing air conditioning costs by as much as 30 percent and saving 20 to 50 percent on energy for heating. This is because as well as providing shade, a large tree can also transpire as much as 378.5 liters (100 gallons) of water into the air per day. This has a cooling effect roughly equivalent to 10 single room-sized air conditioning units operating 20 hours a day!

3)Did trees really kill the dinosaurs?


There is a theory that the evolution of tall, woody, flowering trees (angiosperms) might have played a pivotal role in the extinction of the dinosaurs. It is believed, by some, that the speed at which flowering plants evolved on Earth (possibly spurred on by rapid climate change) occurred too quickly for dinosaurs to adapt their diets. Flowering plants are better at producing oxygen. With the rapid increase in flowering plants, scientists suggest that the metabolism of large herbivorous dinosaurs might have increased to the point that they could not eat enough food to sustain their increased metabolism. Well this theory is hard to believe. But not this one Powerful Plants That Can Purify The Air In Your Home


2)Tree's communicate for self defense 


Trees are masters of both self-defense and communication. Scientists have found that when attacked by insects, trees can flood their leaves with chemicals called phenolics. These noxious compounds are distasteful to tree pests and can even impede their growth. What’s amazing is that once a tree is attacked, it will “signal" to other nearby trees to also start their self-defense, before they are attacked! Methods of communication include releasing chemicals into the wind and possibly even sending chemical or electric signals through the michorizal network of roots (a network of shared fungus fibers). 

1)The oldest living thing on Earth is 80,000 years old 
Although already discussed in one of the earlier post in detail 


The oldest living organism on Earth is believed to be the “Pando" colony of Quaking Aspen (Populus tremuloides) in Utah, also known as the Trembling Giant. The colony of trees covers some 41.7 hectares (103 acres) and is estimated to weigh nearly 6,000,000 kilograms (6,600 tons), making it also the heaviest known organism. Being a clonal colony, the tree “trunks" all share identical genetic makeup. It is estimated that parts of the inter-connected root stock that links the colony together is in excess of 80,000 years old!

Some plants release oxygen in night! Truth or Myth

So we all have heard some of the trees release oxygen even in the night. But is it really a truth or a myth. Lets decipher this fact scientifically but in short.    

 

 Some plants which releases oxygen in night.
Tulsi(Ocimum tenuiflorum)
Peepal(Ficus religiosa)


Snake Plant(Sansevieria trifasciata)



 

The differences in climatic conditions and ecosystems have resulted in different types of photosynthesis in plants.  The three types photosynthesis are C3, C4 and CAM photosynthesis. 


But we will talk about CAM as it happens in night & it is the reason given by every one supporting oxygen at night fact.

 

This type of photosynthesis is most common in desert plants where water is at a premium.  

 

The most important benefit of CAM to the plant is the ability to leave most leaf stomata closed during the day thus saving 97% of water it absorbs.


But from where does it gets CO2 in morning if stomata is closed?????

 

 

 

In CAM photosynthesis, CO2 is taken up only at night.In the morning, sunlight driving the light reactions allows the stored carbon to be combined into sugars.



A common misconception is "Photosynthesis is used to generate oxygen"

  •  Photosynthesis is the process by which green plants, algae and some forms of bacteria use energy from sunlight to convert carbon dioxide and water into glucose.

CONSLUSION:

Yes there are some plants which absorb CO2 even in night but they release oxygen only during the day

But definitely they reduce CO2 level in the night.

 

For better explanation regarding process of CAM refer following articles & Diagrams.
