Recognize Microorganisms based on colour and colony appearance

Lesson Note

Microorganisms, often referred to as microbes, are tiny living organisms that are invisible to the naked eye and can only be seen using a microscope. Despite their small size, microorganisms play a crucial role in various ecological and biological processes. They are found virtually everywhere on Earth, from the deepest ocean trenches to the highest mountain peaks, and even inside the human body.
