Verified step by step guidance1
Understand the historical context: Anton van Leeuwenhoek was a pioneer in microscopy during the late 17th century.
Identify the types of microscopes available during Leeuwenhoek's time: The compound microscope and the simple microscope were the primary types available.
Recognize the characteristics of a simple microscope: It typically consists of a single lens, similar to a magnifying glass, and was used by Leeuwenhoek to observe microorganisms.
Differentiate between a simple and compound microscope: A compound microscope uses multiple lenses to achieve higher magnification, whereas a simple microscope uses only one lens.
Conclude that Anton van Leeuwenhoek used a simple microscope, as it was the tool he famously used to observe and describe single-celled organisms for the first time.
