    Cells are the building blocks of the body. Each cell performs specific tasks like respiration, protein synthesis or nutrient transport. Similar cells form tissues, which group into organs like the heart or lungs. These organs work together in systems to keep the body functioning. Thus, cells coordinate to perform all life activities like breathing, digestion, movement and reproduction.

    Humans could not see tiny organisms with their naked eyes because these organisms are microscopic. They are so small that they remain invisible without special instruments. Before microscopes were developed, people were unaware of their presence or importance in life processes. These tools opened up a whole new world of discovery, allowing scientists to explore life at the microscopic level.

    Lenses got their name from the Latin word “lentil,” as early lenses resembled the shape of a lentil seed—convex and curved. This shape allowed them to bend light, making tiny objects appear larger. Early scientists used these natural shapes to develop magnifying glasses and simple microscopes, enabling the study of microorganisms and minute structures invisible to the naked eye.
