What tool did Leeuwenhoek famously use to observe microorganisms?

• A. Simple Microscope
• B. Compound Microscope
• C. Homemade Magnifying Glass
• D. Electron Microscope

Answer: (C)

Leeuwenhoek’s observation of microorganisms came from simple, single‑lens microscopes that he crafted himself. These devices were basically homemade magnifying glasses with one high-quality lens mounted in a small holder. They weren’t compound microscopes, which use multiple lenses, and they weren’t electron microscopes, which didn’t exist in his time. The power of his simple, handcrafted microscope allowed him to see and describe tiny life forms like bacteria and protozoa for the first time, making the homemade magnifying glass the best descriptor for the tool he used.
