It was a Sunny Morning in Dehradun

I am a regular morning walker and usually out at around 15 minutes to Six in the morning.

Chlorophyll exists in two forms namely Chlorophyll A and Chlorophyll B. It’s production in the plant is dependent upon the amount of sunlight available. It also decays at a continuous rate irrespective… Read More »Chemistry of leaf colors

Winter is here

The winter season is here and I am really afraid.

There is hardly much winter in Mumbai. But now I have returned to North and stay in Dehradun which experiences a very severe winter. The changes are taking place. The sun is rising late each day.
