what is difference between micro organisms and cells
Answers
Answer:
Bacteria were around for about 3 billion years before the first multicellular "complex" life evolved, starting about 1 billion years ago.
All life is based on cells as the primary unit. A bacterium has one cell; you have about 10 trillion. Ironically you also have about 100 trillion bacteria living in your intestines, they help you digest food and process nutrients.
The the major structural differences between a bacterial cell an one of yours is a) our cells have a nucleus where the DNA is stored; bacteria don't. b) bacteria have cell walls to give them structural integrity, our cells don't have such walls, they are enveloped by a flexible membrane instead. and c) Typically, animal cells are about 100 times larger than bacterial cells.
Hope this will help you.
