Diversity of Microbes and Cryptogams

Microbes are single-cell organisms so tiny that millions can fit into the eye of a needle. They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point, hundreds of millions of years before dinosaurs roamed the earth. Cryptogams is a name referring to plants and fungi that do not reproduce by seeds. This book details on the diversity of microbes and cryptogams.
