Study Notes
Basic Biological Concepts
- The cell is the fundamental structural and functional unit of all living beings.
- Cells can exist independently and perform essential life functions.
Microscopy History
- The first microscope was invented by Zacharias Janssen.
- Antony van Leeuwenhoek developed the simple microscope.
- Leeuwenhoek's microscopes achieved a magnifying power of up to 300x.
- He constructed over 500 microscopes throughout his lifetime.
Robert Hooke's Microscope
- Two lenses in Hooke's microscope allowed for enhanced magnification and clarity of the observed object.
- The object was placed in front of the lenses for observation.
- Illumination in Hooke's microscope was achieved using natural light directed at the object.
Leeuwenhoek's Microscope Features
- The lens screw in Leeuwenhoek's microscope was used for precise focusing of the object being observed.
- The observer placed their eye close to the lens for better visibility and detail.
