Q. Omnis cellula-e cellula means :
- new cells are formed from pre-existing cells only
- cells divided to form new cells
- none of the above
- Both of the above
Answer: New cells are formed from pre-existing cell only.
Omnis cellula e cellula, that each cell derives from a pre-existing cell by division, is the culmination of a profound insight of the late 19th century and a dictum articulated by the German pathologist Rudolf Virchow.The generally accepted parts of modern cell theory include:
- All known living things are made up of one or more cells
- All living cells arise from pre-existing cells by division.
- The cell is the fundamental unit of structure and function in all living organisms.
- The activity of an organism depends on the total activity of independent cells.
- Energy flow (metabolism and biochemistry) occurs within cells.
- Cells contain DNA which is found specifically in the chromosome and RNA found in the cell nucleus and cytoplasm.
- All cells are basically the same in chemical composition in organisms of similar species.
Omnis cellula e cellula (each cell stems from another cell)
