What did Robert Hooke see? Examples of early cell observations

📚 Quick Study Guide

• 🔍 Robert Hooke (1635-1703) was a pioneering English scientist.
• 🔬 In 1665, Hooke published Micrographia, detailing observations made through his microscope.
• 🌳 Hooke examined thin slices of cork and observed tiny compartments, which he named "cells" because they resembled the cells of a monastery.
• 📝 Hooke's observations marked a crucial step in the development of cell theory. He didn't see living cells, only the cell walls of dead plant tissue.
• 💡 Antonie van Leeuwenhoek (1632-1723) was the first to observe living cells using his single-lens microscopes.
• 🦠 Leeuwenhoek observed bacteria, protozoa, and other microorganisms, which he called "animalcules."
• 🧪 Early cell observations laid the foundation for modern biology and our understanding of life at the microscopic level.
