Microscopes the invention that started it all.
- In 1609 Galileo Galilei perfected the first device known as a microscope.
- This was important because these microscopes would allow people to be able to see tiny particles and then later form the cell theory.
- I chose this because without microscopes people wouldn't be able to even see cells, it was the invention that made it all possible.

Period: to
Leeuwenhoek cells discovery
- In 1676 Leeuwenhoek wrote a letter to the royal society about motile particle's he saw through his microscope being living organisms. 2.This event is important because he brought up the ideas of some microscopic particles being living organisms.
- I chose this event because Leeuwenhoek was basically the first person to describe cells even though he isn't credited for it.

Period: to
Robert Hook contribution to cells topic.
- Robert Hook was a English physicist who was the writer of "Micrographia" which was very useful to future people and gave a clear description of a cell. 2.He was important because he made "Micrographia" which gave people a description of cells.
- I choose him because I found it interesting that he was given the honor of being labeled as the first person that gave a description of cells instead of Leeuwenhoek.
-
Athanasius Kircher shows people.
- Athanasius Kircher in 1658 showed that maggots and other living creatures developed in decaying tissues.
- This is important because it establishes that tissues are more then they seem and there's something people are missing.
- I chose this because it is what helped started it all research about cells people made other scientist and people to want to learn more.
-
Micrographia
- The work Micrograpia by Robert Hook is widely considered the first important work devoted to microscopical observation, and showed what the microscope could mean for naturalists. 2.This is important because it is considered the first published work about microscopic observations.
- I chose this because it is considered the first known work about microorganisms which makes it one of the starting points into where we are today in this field of study.

Period: to
Lazzaro Spallanzani his disproof of the spontaneous life theory
1.Lazzaro Spallanzani and other researchers showed that an organism derives from another organism and that a gap exists between inanimate matter and life.
2. The conclusion was important because It disproved the theory that water or land can spontaneously generate organisms.
3. I chose this because when there results came and disproved the spontaneous life theory It probably made some people stop looking at the bigger thing and start looking at the smaller things like particles. -
Period: to
Robert Brown the one who came up with the name nucleus
- Robert brown was a Scottish botanis who was the first to recognize the nucleus as an essential constituent of living cells.
- He was important because he named the a part of the cell the nucleus and discovered that it was an important part of living cells.
- I chose him because he was the first to establish the nucleas of a cell as important.
-
Period: to
Theodor Schwann's statement
- Theodor Schwann stated that “the elementary parts of all tissues are formed of cells” and that “there is one universal principle of development for the elementary parts of organisms... and this principle is in the formation of cells”13.
- This is important because his conclusions along with another persons is considered to represent the official formulation of cell theory.
- I chose this because he is an important part of the official formulation of cell theory.
-
Matthias Jakob's suggestion of cells
- Matthias jakob mad3e a suggestion to people that every structural element of plants is composed of cells or their products.. The following year, a similar conclusion was elaborated for animals by the
- This was important because it opened people's eyes to if plants have cells.
- I chose him because of the fact that he was bringing the idea of plants into the cells topic.
-
Period: to
Cell Theory final conclusion
- After the countless researchers conclusions cell theory was finalized as A theory that states that all organisms are composed of one of more cells, that cells are the basic unit of structure and organization of all living organisms and finally that cells arise from previous existing cells.
- This is important because it is what cell theory is.
- I chose this because this is how the cell theory timeline would end as this is the final conclusion. It is what is last in this timeline.
