Cell theory was proposed by
Show Hint
Matthias Schleiden and Theodor Schwann were German scientists and co-founders of the cell theory. Both scientists worked on cells and postulated the cell theory.
- Virchow
- Schleiden and Schwann
- Robert Hooke
- B. McClintock
The Correct Option is B
Solution and Explanation
Cell theory was proposed by German Botanist Malthias Schleiden and British zoologist Theodore Schwann in the year 1839.
The cell theory states the following postulates:
- Cells are the building blocks of all living organisms.
- Pre-existing cells are used to develop newer cells.
- All cells are similar in their chemical composition.
- In living organisms, cells are the essential units of functionality and structure.
- All energy flow of life occurs within cells.
- During cell division hereditary information is passed from one generation to another

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
