Cell (The fundamental unit of life)

Latin world for cell is "cellula" which means 'a little room'.The word 'cell' has derived from the above Latin word 'cellula'.The British botanist Robert hooke while examining a bottle cork under the microscope made by himself, observed room like structutes as in a honey comb. He named the little rooms of the honey comb as cells. Actually he has  seen only the cell wall.
                              All the living organisms are made up of cells. There are some organisms of which the body is made up of only one cell. They are called unicellular organisms. Organisms with more than one cell are multi cellular organisms.
                            It was MATTAIAS SCHLEIDEN in 1838 who first proposed the idea that all plants consist of calls.

The Beauty of Sri Lanka

 
Once they called her the “Glittering petal of the Indian ocean". And again as  "The Living paradise on earth".  Further  they went on to say "The Isle of virtue";"The barn of far east". Now it is the Sri Lanka; 
our motherland. Endowed with natural & cultural beauty, she marches through 21st century.
                 With wide diversity of nature, she host most of living beings of animals & plants, prevail on earth. Travelling through the country, experiencing the typical tropical conditions of sandy breathtaking beaches, wetty & watery  feeling of rainy forests and cool, breezy, misty secludes of mountains  , are a matter of few hours. Populated by a nation; nourished by the teachings of Great Buddha, she inherits a rich culture, which runs over 2500 years of written history and her  warm, welcoming holspitality has largely spread all over the globe too.
