🔑 Key Concepts & Definitions

• Microscope: An optical instrument that magnifies small objects, making them visible to the human eye.
• Lens: A curved piece of glass that bends light to magnify objects; early lenses were simple magnifying glasses.
• Cell: The basic structural and functional unit of all living organisms, first observed by Robert Hooke.
• Micrographia: A book published in 1665 by Robert Hooke, containing detailed drawings of microscopic objects.
• Microorganisms: Tiny living beings, often single-celled, that cannot be seen with naked eyes; include bacteria, fungi, and protozoa.
• Father of Microbiology: Antonie van Leeuwenhoek, who improved lenses and first described bacteria and blood cells.
