Microscopy

Definition

Microscopy is the technique used to view small objects that are not visible to the naked eye, employing various types of microscopes to magnify specimens for detailed observation. This method is essential in many biological sciences as it allows for the examination of cellular structures, tissues, and even whole organisms at a microscopic level. By enhancing visibility, microscopy plays a vital role in understanding plant classification, cell wall composition, and developmental processes.
