Introduction

There are different kinds of organisms in the world. Some are too small, they can

not be seen with naked eyes. Such organisms are called micro-organisms. Others
can be seen with the naked eyes and are called macro-organisms. Due to the
existing diversity of organisms, it is difficult to correctly identify and determine
