The Science Behind Transpiration: Do plants sweat?

Transpiration in Plants

Transpiration is the loss of water from plants in the form of water vapour.

Imagine, during your summer vacations, you go to play football outside. The Sun is scorching hot. One thing you need right now, more than scoring a goal, is a bottle of water! Any living being for that matter needs the same. Do you think plants also need the same?

Yes, they do.

In fact, the water does not magically disappear from a plant. Plants lose water from them through a process called transpiration. 

Transpiration happens in part because plants need to breathe. Plants need to take in carbon dioxide and to do this, they need to open their stomata. When this happens, water comes out

 

Transpiration is the process by which moisture is carried through plants from the roots to small pores on the underside of leaves, where it evapourates to vapour and is released to the atmosphere.

Transpiration Water Cycle

This release of water vapour into the atmosphere, through transpiration, creates a water cycle. It is called the transpiration water cycle. It occurs when:

 

  • The water from the nearby soil is absorbed into the roots due to the hydraulic conductivity of the soil and the magnitude of the pressure gradient through the soil.
  • The water flows from the roots to the leaves. This is driven by capillary action (Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules).
  • The water from the leaves enters the atmosphere. The water potential in the surrounding air is lower than the water potential in the leaf airspace of the stomatal pore. Due to this, water vapour from the cells in the leaves enters the atmosphere as water vapuor. This process is known as transpiration.
  • The water vapour in the atmosphere now forms clouds through the process of condensation. 
  • And these clouds of water vapour turn into water droplets and fall back on earth through the process of precipitation
  • This water that falls on the land, is then absorbed by the soil and is used to nourish the plants. 

This cycle keeps repeating and hence, is called the transpiration water cycle.

Tactivity

You will hardly need anything for this tactivity. If you have a broad leaved plant in your garden, then it is well and good, otherwise you can always head to the nearest park and look for the same.

All you need to do is wrap a plastic sheet around the leaf and close it tightly. Wait for a few hours and you will see water droplets inside the plastic sheet, as though the leaf has “sweat” – or  TRANSPIRED – as  shown in the video below:

The One True Way To Make Learning Fun For Your Child

Fun? What’s that?

After a  long day at work, you come back home exhausted and you just want to sleep. But then you remember that your little one has his homework to do.

With the diminishing energy that you have, you sit with him to do his homework, only to see him apathetic and unresponsive to your attempts at making him study!

Well, if this is the case, then I can assure you, you’re not alone.

The Plague

Education in India is continually found guilty of being mundane and pro-rote methods. We can definitely empathise with our kids on this one, as we ourselves have been victims of this education system. 

Children Studies
Make learning fun for children

The one thing our kids focus on while they sit there “ardently” studying is, when they can go back to play

We have always categorised School and games as mutually exclusive. But, can there be a fun way to integrate the two and give our children the fun they seek, whilst giving them the knowledge that they require? 

The Trick

Yes, the very scarce, yet obvious solution to this would be to integrate the polar opposites of fun and education.

According to a report by Jessica Sanders in her Market Analysis blog, 70% of teachers have seen that implementing games in their teaching aids increases the response they get from students, yet only 18% of them are implementing them.

This is the reason why ThinkTac has come up with a range of fun and games to redefine how schools teach in India.

Benefits of the Integration

I can assure you that the benefits to this integration are endless but here are my top few:

  1. Deep-rooted understanding: When youngsters play a game, they tend to go through the instructions and technicalities more carefully. As they are aware that these need to be recalled at a point later in the game. The perks of knowing the terms and complex jargon are more exciting in a game vs. a mundane Monday morning lesson.
  2. Dealing with Failure:  Games transform the discomfort and mental hurdle that ‘failure’ can create and turns it into an opportunity to master the task at hand.
  3. Increasing the attention span: With the advent of smartphones, the attention span of the younger generation has been on a big decline. With the focus needed in video games, your kid can now have a platform to work on the dearth of his concentration. 
  4. Less to worry: Going back to the point of you coming back exhausted from work, you can now be rest assured that your child is studying wisely and you can finally sleep peacefully!

At this note, I shall leave you with some food for thought. 

When we make play the foundation of learning, we teach the Whole Child.

We also have a really cool competition for your innovative little genius, check it out here.

Road To Innovation

The young India needs to adopt the same approach and enthusiasm like they did for #HumFitTohIndiaFit Challenge, by supporting our country’s “Future Ready” vision. 

You may be wondering that the Fitness challenge was endorsed by A-list celebrities and personalities, in order to successfully spread the message. 

Then how can YOU make a difference?

Let’s not forget that you have the eye as you are the reason why the Influencers are able to influence us, in the first place. 

Be the Influencer

There may be no shortcuts to success, however walking on the footsteps of the renowned Scientist, Albert Einstein, may certainly lead you to your destination.

“The true sign of intelligence is not

knowledge but imagination.”

-Albert Einstein

Final Destination

Don’t worry, it’s not as stressful as the movie. 

Raman Search Institute Trust and ISPF (Innovation and Science Promotion Fund) institutes Raman Young Science Innovator (RYSI) award year after year because we can’t get enough of the young minds taking over the world. 

Today’s science is tomorrow’s technology.

If you think your child has it in you to contribute to his/her Nation and receive the much awaited recognition in the field of Science. Sign them up, now.

Your child’s imagination, can be India’s biggest innovation.

Last time we embraced 8500 registrations from all over India (including rural areas), and 1700 submissions.

There were 114 finalists contributing to the success of these events and motivating us to serve as stepping stones for a developed passion for Science. 

Walk this path with your child and see the sparkle in their eyes when they realize that sky is the limit.
