Human Cheek Cell Experiment

The video tutorial from Manocha Academy guides viewers through preparing a temporary slide of human cheek cells. It emphasizes safety precautions, lists necessary materials, and provides step-by-step instructions for collecting cheek cells, staining them, and observing them under a microscope. The tutorial concludes with a summary and directs viewers to additional resources on the academy's website.

What is the main objective of today's virtual practical class?
