Project report on microorganisms friend and foe

Answer 1

Activity 2.1 Collect some moist soil from the field in a beaker and add water to it. After soil particles have settled, observe a drop of water from the beaker under a microscope. What do you see ? Activity 2.2 Take a few drops of water from a pond. Spread on a glass slide and observe through a microscope. Do you find tiny organisms moving around? These observations show that water and soil are full of tiny organisms, though not all of them fall into the category of microbes. These microorganisms or microbes are so small in size that they cannot be seen with the unaided eye. Some of these, such as the fungus that grows on bread, can be seen with a magnifying glass. Others cannot be seen without the help of a microscope. That is why these are called microorganisms or microbes. Microorganisms are classified into four major groups. These groups are bacteria, fungi, protozoa and some algae.
