Hooke
By using a microscope, Hooke observed slices of corks, plants, and a fly's eye and discovered cells.
Hooke is the person that created the term "cells" meaning the smallest unit of life. -
Leeuwenhoek
Leeuwenhoek discovered a bee's mouthpart (single-celled) using a microscope that he had made, which was more improved than Hooke's microscope.
Leeuwenhoek, after he made his discovery, wrote letters to the society and other scientific institutes. -
Dujardin
Dujardin began classifying the single-celled organisms.
He found a formless life substance which ws later known as Protoplasm.
Instead of just finding these single-celled organisms like the previous scientists, he put classification and a name to them. -
Dutrochet
Durochet was the first to recognize the importance of cells and the first to recognize how similar plant and animal cells were.
Dutrochet was the scientist that recognized that cells were a very fundamental part of life.
He made these discoveries by looking at plant cells and discovered the importance of the green pigments and the function of it. -
Schleiden
Schleiden studied plant structures under a microscope and discovered that parts of the plant are complosed of cells and the importance of the cell nucleus. He was the first scientist to look into the cells of a plant more closely.
He wrote “Contributions to Phytogenesis.” -
Schwann
Schwann discovered an enzyme by isolating a substance responsible for digestion in the stomach. he said that this was the basic unit of animal life.
He published "Microscopical Researches into the Accordance in the Structure and Growth of Animals and Plants."
He also extended Schleiden's cell theory to the cell theory of animals. -
Virchow
Virchow discovered that all living things come from other living things, and all cells come from other cells.
He furthered the theory by discovering diseases under the microscope and naming them.
