Who was the first scientist to observe a cork?
In 1665, Robert Hooke was the first to observe cork cells and their characteristic hexagonal shape, using the first optical microscope, which was invented by him at that time.
Which scientist first viewed cork cells with a light microscope?
Robert Hooke The first person to observe cells was Robert Hooke. Hooke was an English scientist. He used a compound microscope to look at thin slices of cork.
What is the name of the scientist that viewed cork under the microscope and called the boxes cells?
Hooke The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory.
Who observed cork cells?
Robert Hooke The cork was full of small empty compartments separated by thin walls. He called the compartments "pores, or cells." He estimated that every cubic inch of cork had about twelve hundred million of these cells. Robert Hooke had discovered the small-scale structure of cork.
Who studied cork?
Hooke was one of the earliest scientists to study living things under a microscope. The microscopes of his day were not very strong, but Hooke was still able to make an important discovery. When he looked at a thin slice of cork under his microscope, he was surprised to see what looked like a honeycomb.
What did Anton van Leeuwenhoek discover?
Leeuwenhoek is universally acknowledged as the father of microbiology. He discovered both protists and bacteria (1). More than being the first to see this unimagined world of 'animalcules', he was the first even to think of looking—certainly, the first with the power to see.
What did Theodor Schwann discover?
In 1848 Schwann accepted a professorship at the University of Liège, where he stayed for the remainder of his career. At Liège he investigated muscular contraction and nerve structure, discovering the striated muscle in the upper esophagus and the myelin sheath covering peripheral axons, now known as Schwann cells.

What did Schleiden and Schwann discover?
Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.

What did Robert Koch do?
Robert Koch was the man who, building on the work of Pasteur and Lister, set bacteriology on its way to being a modern science. He discovered the causative organisms of anthrax, septicæmia, tuberculosis and cholera.
What did Theodor Schwann discover about the cell theory?
Schwann, Theodor In 1838 Matthias Schleiden had stated that plant tissues were composed of cells. Schwann demonstrated the same fact for animal tissues, and in 1839 concluded that all tissues are made up of cells: this laid the foundations for the cell theory.

After isolating the mold and identifying it as belonging to the Penicillium genus, Fleming obtained an extract from the mold, naming its active agent penicillin.
