cells

red blood cells

1658

Jan Swammerdam discovered oval red corpuscles. I chose this because it was the first discovery of any type of cell.

cork cells

1665

Using a microscope, Hooke looked at a cork and named the structures inside of it cells. This is important because its where cells got its name

the microscope

1830

the microscope was invented around the 1830s, giving scientists the opportunity to take a closer look at cells and how they work.

nucleus

1831

robert Brown discovered that all cells need a nucleus in order to survive. I added this information because a nucleus is an important part of cells.

plant cells

1838

matthias Jakob found out that all plants are made up of cells. This is important because there are so many different plants, that its impressive how this was discovered.

animal cells

1839

Theodor Schwann discovered that all animals are made up of cells. Because we already know that all plants have cells, this means that all living creatchers are made up of cells.

drawings

1865

Karl Deiters published a diagram of what nerve cells look like. This is significant because the rest of the population could see what they look like and not just scientists.

black reaction

1873

Golgi developed the black reaction, which showed the process of a nerve cell. I chose to add this because its where we started to understand how nerves work.

Mitosis

1882

cell division was given the mane mitosis. this is important because cells multiplying is a very strange concept to grasp.

neuron theory

1891

Waldeyer introduced independent nerve cells called neurons, which is important because it aided in the discovery of the nervous system.
