Reading Check 1. Explain Why is a microscope needed to view most cells?

Most cells are so minuscule that they fall below the threshold of visibility for the human eye, which is about 0.1 millimeters. A microscope amplifies the size of these tiny structures, allowing us to observe cells in detail, such as their shapes and internal components. This amplification is crucial for understanding cellular functions and interactions, forming the foundation of fields like biology and medicine! Without microscopes, we’d be left guessing about the vast and vibrant world of microscopic life, much like trying to solve a puzzle with half the pieces missing! Imagine scientists peering at different specimens, from observing microorganisms in pond water to studying human tissues. The ability to magnify tiny details has opened doors to amazing discoveries, including the roles of cells in health and disease!
