Bacteria cannot be seen with the naked eyes, but these can be seen with the help of a microscope. If you have to carry a sample from your home to your biology laboratory to demonstrate the presence of microbes under a microscope, which sample would you carry and why?

Curd can be preferred as sample from home to observe bactaria in laboratory. A small amount of curd contains large amount of lactobacillus which could be observed under light microscope using normal staining methods. Lactobacillus also known as lactic acid bactaria. They convert milk into curd by producing lactic acid.
