The Cell – The Chemistry Of Life (BBC HD Documentary)


The second episode explores how scientists delved ever deeper into the world of the cell, seeking to reveal the magic ingredient that can spark a bundle of chemicals into life. Their discoveries have brought us to the brink of being able to create life for ourselves. This three part series tells the extraordinary story of the scientific quest to discover the secrets of the cell and of life itself. Every living thing is made of cells, microscopic building blocks of almost unimaginable power and complexity. The cell is the functional basic unit of life. It was discovered by Robert Hooke and is the functional unit of all known living organisms. It is the smallest unit of life and is often called the building block of life. In 1835, before the final cell theory was developed, Jan Evangelista Purkyn observed small „granules“ while looking at the plant tissue through a microscope. Cell theory, first developed in 1839 by Matthias Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that all cells come from preexisting cells, that vital functions of an organism occur within cells, and that all cells contain the hereditary information necessary for regulating functions and for transmitting information to the next generation of cells.
