nineteenth century.​

Answer 1

The statements of the Cell Theory are as follows:

• The cell is the structural and functional unit of life.

• All living beings are made up of one or more cells.

• Every cell is obtained from pre-existing cells.

The cell-theory was given by 3 scientists

• Theodor Schwann

• Mattias Schleiden

• Rudolf Virchow

An exception to cell theory

• Virus

Explaination of cell theory:

• Cell theory states that the cell is the basic building block of any and every organism and is also responsible for all the functions.

• The theory also states that every organism may contain one cell (unicellular) or many cell (multicellular).

• Each cell arises from preexisting cell by cell division and proliferation

Answer 2

Answer:

cell theory:- the 1st cell was observed by Matthias sheilden. he was a German botanist and observe different kind of cells in plants.

• the 2 most important statement in theory are  

• omnis cellula e- cellula which means all cells are arising from pre-existing cells.

• and all living organisms are made from cells and their cell products.

• these 2 statements are very important in the 19th century  

• Rudolf Virchow was a scientist who gives the statement Omnis cellula -e cellula.

• he gives the modifies form of cell theory which was already given by Schwan and Schleiden.

• Schwann was a British zoologist he reported the plasma membrane and different types of animal cells also.

• this all theories prove that living organisms are arise from the pre-existing cell and no new cells are formed every time.

• These theories also give birth for research on evolution. that then how the 1st cell form if all living organisms arise from pre-existing cells.
