What was the first cell observed through the microscope?
While observing cork through his microscope, Hooke saw tiny boxlike cavities, which he illustrated and described as cells. He had discovered plant cells! Hooke’s discovery led to the understanding of cells as the smallest units of life—the foundation of cell theory.
Who 1st discovered cells using a microscope when?
Robert Hooke (July 18, 1635–March 3, 1703) was a 17th-century “natural philosopher”—an early scientist—noted for a variety of observations of the natural world. But perhaps his most notable discovery came in 1665 when he looked at a sliver of cork through a microscope lens and discovered cells.
Who was the first scientist to discover cells?
Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements.
Who is the first scientist that discovered cell?
When was the first microscope invented?
In around 1590, Hans and Zacharias Janssen had created a microscope based on lenses in a tube . No observations from these microscopes were published and it was not until Robert Hooke and Antonj van Leeuwenhoek that the microscope, as a scientific instrument, was born.
Who discovered the microscope?
Every major field of science has benefited from the use of some form of microscope, an invention that dates back to the late 16th century and a modest Dutch eyeglass maker named Zacharias Janssen.

Where was the first microscope invented?
Spectacles first made in Italy. Two Dutch spectacle-makers and father-and-son team, Hans and Zacharias Janssen, create the first microscope. Robert Hooke’s famous “Micrographia” is published, which outlines Hooke’s various studies using the microscope.
How did Robert Hooke discover cells?
Hooke viewed a thin cutting of cork and discovered empty spaces contained by walls which he termed cells. When Hooke viewed a thin cutting of cork he discovered empty spaces contained by walls, and termed them pores, or cells. The term cells stuck and Hooke gained credit for discovering the building blocks of all life.
What was Robert Hooke’s microscope?
Hooke’s Microscope. This beautiful microscope was made for the famous British scientist Robert Hooke in the late 1600s, and was one of the most elegant microscopes built during the period. Hooke illustrated the microscope in his Micrographia, one of the first detailed treatises on microscopy and imaging.
What is Hooke cell theory?
The Cell Theory. Robert Hooke (1635-1703) first described cells in 1665. Modern cell theory includes four principles: All living organisms are composed of cells. Nothing smaller than a cell is considered to be alive. Life evolved only once, and all living organisms have descended from the earliest cells.
What was Robert Hooke’s contribution to the cell theory?
Cell Theory. Robert Hooke contributed to the cell theory by introducing the world to “cells”. His discovery was made by observing a thin cutting of cork and finding walls with empty space, he named these spaces “cells.”.
