Teory of Cell

Cell theory is an important material that we must understand in studying biology .
 As we know that the Cell is the smallest structural and functional unit that composes the body of a Living Being.
Who is the first person to find a cell? Who are the scientists who think about cell theory? What is the sound of the cell theory they put forward?

Everything will be discussed here.

Cell Pressure

Many scientists have researched and concluded that plants and animals are composed of cells. Starting from the 18th century to the beginning of the 19th century. However, cell theory at the time was still debated.

In 1838, the German botanist Matthias Jakob Schleiden stated that all plants consist of cells and all the functions of the plant body are basically cell activities.

He also stated the important role of the nucleus (which Robert Brown discovered in 1831) in cell activity and cell reproduction . Although he thinks that cells are formed from the nucleus.  In 1839, Theodor Schwann, who had discussed with Schleiden, realized that he had observed the nucleus of animal cells as Schleiden observed them in plants.

He stated that all parts of the animal's body are also composed of cells. According to him, all tissues in living things (organisms) are composed of cells. Then cell theory was introduced in more detail by Rudolf Virchow , a German scientist. At first he agreed with Schleiden regarding cell formation. Microscopic observations of various pathological processes led him to conclude the same thing that had been concluded by Robert Remak .  Robert Remak had previously observed red blood cells and embryos. The conclusion is that ' cells come from other cells through cell division ' .


In 1855, Virchow published a famous paper, omnis cellula e cellula (all cells derived from cells).

Robert Hooke

Robert Hooke is the first person to name a cell or can be called the first person to find a cell. The term cell was discovered by Robert Hooke after observing a dry cork incision.

Initially in 1665 a British scientist Robert Hooke examined the thin slices of cork through a microscope that he designed himself. The word cell comes from the Latin word cellula, which means space.
In 1835, before the cell theory was defined as the smallest organizational unit that composed living things. All functions of life are regulated and take place in cells. Because of this, the cell can function independently as long as all of its life needs are met.

Scheilden and Schwann

Cell Theory according to Scheilden and Schwann states that 'Cells are structural entities'

Scheiden and Schwan are scientific figures who are very instrumental in the world of microbiology, with cell theory is a structural unity (based on form). Scheilden observed cells in plants and Schwann observed cells in animals. The following are the results of his observations:

Animal Cells

1. Does not have a cell wall
2. Don't have plastids 
3. Having lysosomes 
4. Have centrosomes 
5. The accumulation of substances in the form of fat and glycogen 
6. Non-permanent form 
7. In certain animals have vacuoles, small size, little.

Plant Cells

1. Has a cell wall and cell membrane
2. Generally has plastids 
3. Do not have lysosomes 
4. Don't have centrosomes 
5. Substances in the form of starch 
6. Fixed shape 
7. Has a large vacuole, lots

Max Schultze

Cell Theory according to Max Schelze reads ' Cells are functional units '

His name is very well known for his work on cell theory. By combining Felix Dujardin's theory of the concept of "sarcode" in animals with Hugo von Mohl with protoplasm in vegetables, he unites the two and the two things are included under the common name protoplasm, defining cells as nucleated masses of protoplasm with or without cell-wall ( Das Protoplasma der Rhizopoden und der Pflanzenzellen; ein Beiträg zur Theorie der Zelle , 1863).

Rudholf Virchow

Cell Theory According to Rudolf Virchow who said that 'All cells come from cells ( omne cellulae e cellula )'

Virchow was instrumental in many important discoveries. Although he and Theodor Schwann were not mentioned together, he was most widely known because of his theory of cells. He was the first to find leukemia cells.

Rudolf Virchow was the first person to accept and trace the work of Robert Remak who stated the origin of the cell was the division of the previous element. This theory was stated in the paper Omnis cellula e cellula (each cell came from the previous cell) which was published in 1858. This paper also denied the theory of living things from inanimate objects.

Thomas Huxley

Thomas Huxley stated that his cell theory which is called 'Cell is a physical unit of chemistry'.

Watson and Crick

Theory Cells deflect Watson and Crick are cells that are a unit of heredity

Robert Brown

The theory of cells according to Robert Brown is 'In the cell there is a cell nucleus (nucleus)'

Robert Brown is a Scottish botanist who made an important contribution to botany through the discovery of cell nuclei and cytoplasmic flow. The first observation of the Brown Movement is the initial research on pollination and fertilization in plants.

Brown was also one of the first to recognize the fundamental difference between the plants of gymnosperms and angiosperms, and did an early study of palinology. He also contributed a lot to the taxonomy of plants, including the classification of a number of plant families that are still accepted today and many genera and Australian plant species, the results of which are explored along with Matthew Flinders

Felix Dujardin

The theory of cells by Felix Dujardin is 'Inside every cell of living things there is a cytoplasm'
