Question: Who discovered Cell and How?
- Antoni van Leeuwenhoek
- Galileo Galilei
- Isaac Newton
- Robert Hooke
Answer: D. Robert Hooke
Who discovered Cell and How? Solution:
Robert Hooke discovered the cell in 1665 while observing a slice of cork under a microscope. He saw that the cork was made up of tiny compartments, which he called “cells”. Hooke’s discovery of the cell was a breakthrough in biology, and it led to the development of the cell theory, which is one of the fundamental theories of biology.
The cell was discovered by Robert Hooke in 1665. While examining a thin slice of cork under a microscope, he observed tiny, box-like structures, which he named “cells” due to their resemblance to the small rooms occupied by monks. Hooke’s work marked a significant milestone in biology, as it was the first time the fundamental unit of life was identified. His findings laid the groundwork for cell theory, which later evolved through the contributions of scientists like Anton van Leeuwenhoek, who discovered living cells, and Matthias Schleiden and Theodor Schwann, who formulated the principles of cell theory.
Who is the Father of Geography?
The title “Father of Geography” is commonly attributed to the ancient Greek scholar Eratosthenes. Born around 276 BCE in Cyrene, he made significant contributions to the field by introducing the concept of latitude and longitude. Eratosthenes was the first to calculate the Earth’s circumference with remarkable accuracy using simple geometry. He also compiled a comprehensive map of the known world, integrating knowledge from various sources. His work laid the foundation for future geographical studies and inspired many scholars. Today, Eratosthenes is celebrated not only for his geographical insights but also for his contributions to mathematics and astronomy, solidifying his legacy in history.
