What scientists made a contribution to cell theory?

Answer 1

The word cell was first used by English scientist Robert Hooke in 1665 to describe the cell walls visible in cork when seen through a microscope.

In 1838 the German botanist Matthias Schleiden concluded that all plant tissues were made of cells. In 1839 the zoologist Theodor Schwann reached the same conclusion about animal tissues.

By 1885 the German physiologist concluded that cells only originated by the division of a preexisting cell.

Answer 2

Scientist...... Contribution......

Hooke (1600's) 1st person to identify and name a cell

Schleiden (1800's) Botanist (studies plants) all plants made up of cells

Schwann (don't know Zoologist (studies animals), all animals made up of cells

the time period)

I remembered this for my test by schwann sounding like a bird and a bird is an animal. Hooke has an E at the end of it and cell has an E. Or Hooke like captain Hook and he should go to jail and another word for jail is a 'cell'. I remembered Schliden because it was the last one left with plant.

Answer 3

-Robert Hooke discovered the cell

-Antonie Von Leeuwenhoek first saw it under the microscope

-Ludolph Christian Treviranus and John Jacob Paul Moldenhawer idea that cells were separable.

Answer 4

The Cell Theory was developed from three German scientist's discoveries. They are Matthias Schleiden, Theodor Schwann, and Rudolph Virchow. In 1838 the German Botanist Matthias Schleiden discovered that all plants were composed of cells. Then only a year later a German zoologist, Theodor Schwann, discovered that all animals were composed of cells. Later in 1855 a German physician named Rudolph Virchow was doing experiments with diseases when he found that all cells come from other existing cells. Cells of course were discovered much earlier. The first person to see a cell was Robert Hooke. He used a very primitive microscope, but when he was looking at cork cells under the microscope he saw cells for the first time. The shape of the cells reminded him of the monk monasteries and so he dubbed them "cells." The first person to see living cells was Van Leeuwenhoek, a microscope builder.

Answer 5

The discovery of the cell is the key event that led to our understanding of life. It is instructive to trace
the development of this concept starting with Robert Hooke’s view of the cell as a nondescript 'box' in the late 1600s.
Centuries later, the cell was treated as a “bag of enzymes”; later still, the organelles were discovered one-by-one; then came Lynn Margulis’s hypothesis that the eukaryotic cell arose as a colony of symbiotic organisms.
With every passing decade, our conception of the cell becomes more complex. Advances in medicine depend upon a deep understanding of cells, cell receptors, enzymes, and organelles. For example, many clinical tests quantify proteins, nucleic acids, metabolic intermediates, and blood cells.
But three scientists are usually given credit for its development: Matthias Schleiden, Theodor Schwann, and Rudolf Virchow.

Answer 6

Robert Brown, Rudolf Virchow, Matthias Schleiden, and Theodor Schwann all said the same thing..... "Every living organism has living cells in them''.

Answer 7

The first scientist who first discovered cell theory was Robert Hooke.

Answer 8

Microbiologists and Virologists

Answer 9

-Henri Dutrochet modern cell theory.
