2. What do we know about them? Can we see viruses and bacteria with the naked eye? Why? Where do bacteria and viruses live? What is biological importance of their existence in the nature? Who are the protists?

3. What are the microorganisms? A microorganism is a living single-celled organism of microscopic size.

4. Bacteria Bacteria are the simplest living group of organisms and inhabit practically all environments. Common name – PROKARYOTES (without nucleus) Bacteria are the most successful organisms on the planet. They lived on this planet for two billion years before the first eukaryotes and, during that time, evolved into millions of different species.species

5. Bacteria Size and Shape Bacteria are so small that they can only be seen with a microscope. When viewed under the microscope, they have three distinct shapes (Figure below). Bacteria can be identified and classified by their shape:microscopebelow Bacilli are rod-shaped. Cocci are sphere-shaped. Spirilli are spiral-shaped.

6. Protists Common characteristic: EUKARYOTES Very diverse Three general categories: Animal-Like Protists Plantlike Protists Funguslike Protists
