I found that Theodore Schwann found out that all animals are made of cells.

OliviaT said...


1.All organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3.All cells come from preexisting cells.

Zacharias Jansen contributed by coming up with the first compound microscope and telescope.

The three parts to the cell theory are, all organisms are composed of one or more cells, the cell is the basic unit of structure and organization in organisms, and all cells come from preexisting cells. One scientist that contributed to the cell theory is Robert Hooke, who gave cells their name.

In the cell theory there are three parts. Part 1. All organisms are composed of one or more cells.Part 2. the cell is the basic unit of structure and organization in organisms.Part 3. All cells come from preexisting cells. One scientist that contributed to the cell theory is Theodore Shwann he was the one to realize that all animals were made out of cells.

B.H. - there are three parts to the history of cells. One all organisms are composed of one or more cells. Two the cell is the basic unit
of structure and organization in organisms. Three all cells come from preexisting cells. One scientist is Rudolf Virchow and his contribution is having evidence that cells did come from other cells.

Kaleen said...

The first part to the cell theory is all organisms are made out of one or more cell. The next part is that the cell is the basic unit of structures and organization in organisms. Then the last part is all cells come from preexisting cells.
The scientist I am to talk about is Schwahn. He studied animal cells and found out that every thing he looked at was made of cells.

Taylor said...

The three parts to the cell theory are all organisms are made up of cells, the cells are the main organization in organisms, and all cells come from preexisting cells. Theodore Schwann discovered that all livings things were made of cells with the help of Mathias Shleiden.

Alivia said...

The 3 cell theory's are
1 All organisms are made of one or more cells,
2 The cell is the basic unit of structure in organisms
3 All cells are made of preexisting cells.

Matthias Schleiden liked to study plants and every plant he looked at he found out that they were all made of cells, He also found out that all animals are made out of cells too.

Robert Hooke loved all aspects of science he put everything into his writing and then took a piece of a cork under a microscope and saw something that reminded him of cells so he named it cells.

The three parts of the cell theory are: 1, All organisms are composed of one or more cells. 2, The cell is the basic unit of structure and organization in organism. 3, All cells come from pre-existing cells. One scientist who contributed to the cell theory was Matthias Schleiden. As he studied different plants, he came to realize that all plants were made up of cells.

Jocey said...


Robert Hooke got the name cells from a cork cap and there were chamber shaped and it reminded him of the cells that monks slept in ,in their monasteries.
Mat Thais Schleiden discovered that all plants where made of cells.
Theodore Schwann discovered that all animals were made of cells as well.

payton said...

1. All organisms are composed of one or more cels.
2.The cell is the basic unit of structure and organisms.
3.All cells come from preexisting cells.

Anton Van Leewihhook


Anton heard about the microscope and instead of buying one he made him self one. After he had had it ready. He went to town and looked at everything he could. ex. Onions, shoes and flowers etc. Including the gunk on his teeth. He discovered bacteria by looking at dental scrapings. At the time he called bacteria Animalcules. The reason why is he thought they looked like little animals

Makenezieg said...

The three parts to the cell theory are all organisms are composed to one or more cells 2 the cell is the basic unit of structure and organization in organisms 3 all cells come from preexisting cells. The scientist is Anton van Leeuwenhoek who named Anamalclues.

Jocey said...

HERE IS WHAT THEY ARE!!!

#1 All organisms are composed of one or more cells.
#2 the cell is a unit of structure and organism.
#3 All cells are from pre-existing cells.

Nicole said...

The three parts of the cell theory are one all organisms are composed of one or more cells. Two the cell is the basic unit of structrue and organisms in organisms. Three all cells come from preexisting calls. one of the scientist is Robert Hook. Robert Hook's contribution to the cell theory is he was looking at a peace of a cork under his micrascope and the little canbers he saw remined him of cells or the rooms that people slept in so we can thank for the tram cells.

hunter murphy said...

three parts of the cell theory

1.all organisms are composed of more then one or more cells.
2.the cell is a unit of structer and organisms.
3.all cels are pre-existing cells.

I found that the three Parts of cell theory are that all organisms are composed of one or more cells, that the cell is the basic unit of life, and that all cells come from preexisting ones.

One scientist that contributed to cell theory is Anton van Leeuwenhoek who discovered bacteria living on his teeth. Instead of calling them cells he called them animalcules because he thought they looked like microscopic animals.

Abbie B. said...

The three parts to the cell theory are all organisms are made of cells, the cell is the basic unit of life in an organism, and all cells come from other cells. Robert Remak is a scientist who helped contribute to the cell theory with research that proves all cells come from other cells.

Meghan said...

Robert Remaks work was the work that solidified the disagreement about whether or not the third theory was true.

Hayden said...

the tree parts of the cell theory are 1, all the organisms are composed of one or more cells. 2, the cell is the basic unit of structure and organisms with organisms. 3, all the cells come from preexisting cells. ! of the scientist is Robert Hook. Robert Hook's contribution to the cell theory is he was looking at a peace of a cork under his microscope and the little canbers he saw reminded him of cells or the rooms that people slept in so we can thank for the tram cells.

Tyler L. said...

The first part of the cell theory is that all organisms are composed of at least one cell, the second part of the cell theory is "'the cell is the basic unit of structure and organization in organisms"' and the third and final part of the cell theory is every single cell comes from an already preexisting cell/s. A person who widely contributed to the cell theory is Matthias Schleiden. He found out that plants have cells because he studied plants under microscopes.

robert hooke was under a microscope and he saw that something reminded him of little cells, so he named it "cells."

Julia Ryan said...

The three parts of the cell theory is one, all organisms are composed of one or more cells. Two the cell is the basic unit of structure and organization in organisms, and three, all cells come from preexisting cells. One scientist that helped contribute to the cell theory was Mat Thias Schleiden. He studied plants through a microscope. One day Schleiden realized all plants had one thing in common, they are all made of cells. That is how he figured out cells.

Madyson said...

The three parts of cell theory are one, all organisms are composed of one or more cells. Two, the cell is the cell is the basic unit of structure and organization in organisms, and three, all cells come from preexisting cells. Theodore Schwann studied glass slides of animals and he got his own special nerve cell named after him "The Schwann cell", he also at the same time he invented the re-breather that is used for firefighters.

*All organisms are composed of or more cells ,
*The cell is a unit of structure and organisms ,
*All cells are prom pre-existing cells.
*"Living things : Living things need to eat, respire, excrete wastes, and perform all of the necessary functions of life.
so cells stand bye our side , Cells are made up of components that help living things."

Scientist: Rudolf Virchow, he found the research that cells come from pre-existing cells.

The three parts of cell theory are, one, all organisms are made of one or more cell/s. Two, the cell is the main unit of structure and organization in organisms. And three, all cells come from old cells. Mat Thias Schleiden, he was one of the first people to see that all living things are made of cells.

There are three parts of the cell theory that started being created in the early 1600s. the first part of the cell theory was, all organisms are made up of one cell or more, the second being, the organization of living things comes from the cells within the organism. And the last part was created by Matthians Schleiden, he studied plants through microscopes, he relized that all the plants he had been studying were made up of cells. He later worked with another scientist, they came up with the final part of the cell theory, all cells come from other cells.

One scientist that contributed to the cell theory is anton van leeuvenhoek, and think he contributed because he looked through microscope at dental scrapings from his teeth and gums and discovered bactieria then people started to discover cells.

Anonymous said...

One part to the cell theory is that all organisms are composed of one or more cells. Two: the cell is the basic of structure and organization in a organism. Three: All cells come from other cells that know longer exist.
One scientist that had contribution to the cell theory is Zacharias Janssen which made a microscope which then went viral and everybody wanted them so he contributed the microscope.

Maia K. said...

Cell theory was not discovered by just one scientist, but by many! 3 of them are, Anton Van Leeuwenhoek, Matthias Schleiden, and Theodore Schwann. Leeuwenhoek discovered bacteria by looking at his teeth with a microscope; Schleilden and Schwann helped tie the Cell Theory as we know it together. What is the Cell Theory? The Cell Theory is comprised of three different rules:
-All Organisms are made up of one or more cells
-All Cells are made by already existent cells
-And the Cell is the basic unit of Organization and structure in any living thing.

Allie said...

Matthias Schleiden. All organisms are composed by one or more cells. The cell is a basic unit of structure. All cells come from preexisting cells.

Grace.D said...

cells came from pre existing cells, all organisms are made of more than one cell, the cell is the basic unit of life for an organism.


matthias schleiden, found out that all the plants around were made of cells

cells come from other cells only

Kaylah S said...

1 All organisms are composed of cells
2 Cells are alive and the basic living units of organization in all organisms.
3 All cells come from other cells.
Theodore Schawann found out that animals are also made of cells.

All living things have to be made out of cells and those cells came from pre-existing cells but all living things at least one or more cells to be a living thing.

Allie D. said...

There are three parts of the cell theory, these include all organisms are made of cells, the cell is the basic unit of life, and all cells come from other cells. Anton Van Leeuwenhoek was a scientist that contributed to the cell theory. He contributed to the cell theory by looking at many things with his microscope that he made. That is about the cell theory.

These are the three parts of the cell theory. The first one is all organisms are composed of one or more cells. Next is the cell is the basic unit of structure and organization in organisms. Finally, all cells come from preexisting cells. One of the scientists that contributed to the cell theory, was Robert Hooke. Hooke was looking at cork under his microscope and and the little things he found looked like cells to him. Thats where we got the term cell. Issac Newton and Hooke were very big rivals. when Newton published a book about gravity, Hooke said he already knew that and he made sure people knew that. Also a fun fact is that after Hooke died, Newton became angry and stole all of Hooke's remaining things. They were found in the future, but never his portrait. so we never know what Robert Hooke lokked like to this day.

Their are three parts to the cell theory. The first part is, all living organisms are made up of one or more cells. Secondly, the cell is one of the main parts of the organization and structure of the organism. Lastly, all cells come from past or preexisting cells. Meaning their is not a such thing as a new cell in an organism. I know that a microscope must have helped in the discovering of the cell theory and the creator of that microscope was Zacharias Janssen.

Anonymous said...

robert hooke studied the cell theory and the three parts of the cell theory is All known living things are made up of one or more cells,
All living cells arise from pre-existing cells by division, and that The cell is the fundamental unit of structure and function in all living organisms.
