"These are old organizations of the country which have laid the foundation stone of modern India. This stamp was released to remember the contribution of hundreds of scientists working in this field," he said.
Prasad said that his ministry was focusing on use of Information and Technology in spreading awareness about the extent of biodiversity found in the country.
Highlighting the importance of mobile and internet, Prasad had earlier said that by December, India will have 40 crore internet users, overtaking US, and will be second only to China.
In the global telephone subscriber base of 102 crore, India has 98 crore mobile users, he said.
