Introduction to Cell Biology[edit]

It is easy to recognize life. Cats, trees in our gardens, ourselves, etc., are all alive. Computers, the air we breathe, waterfalls, etc., these are not alive. But what is life? What makes living beings different from sand, water?

Cell biology tries to answer what life is, where it comes from and how it functions. From that, cell biologists draw a general rule for all living things on Earth.
