Autumn, the Year’s Last, Loveliest Smile

SubscribeFiled Under: Photo Essay,by Neeraj

Autumn – It’s a time of the year when nature treats us to a symphony of colours. The changing colours of tree leaves, ranging from yellow to orange, are a real treat for the eyes. It is no wonder that numerous poems are composed in dedication to this magical season.
 
The photo essay is an attempt to capture the beauty of “fall colours” as seen in early October in Southern Ontario. The captions will help explain the science behind this wonderful phenomenon in layman’s terms.

Did you know that leaves are a plant’s food factory?

In a process called photosynthesis, plants use sunlight to turn water from the ground and carbon dioxide from the air into glucose (sugar) and oxygen.

Plants use glucose as food for energy and as a building block for growing.

 Photosynthesis is made possible due to a chemical called chlorophyll.

Chlorophyll is what gives plants their green colour.

As summer ends, the days get shorter and shorter and plants receive less and less light and water for photosynthesis.

The plants thus begin to shut down their food-making factories and the green chlorophyll beings to disappear from the leaves.

 So the yellow and orange colours that we see are because the green is fading away.

The photo above shows the beautiful fall colours and also, what I would like to call, “a hidden gem” that I recently discovered – I will have more on that later!
