Question

How would you demonstrate that all cells come from preexisting cells

Answer 1

Answer: The generally accepted parts of modern cell theory include: ... 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.

Explanation:

Answer 2

To demonstrate that all cells come from pre-existing cells, you should: Observe a bacterium performing binary fission to form clones of itself.

A cell can be defined as the basic functional, structural and smallest unit of life which is found in all living organisms.

According to cell theory, the following statements are true about cells;

• All living organisms comprises small structural units called cells.

• A cell is the fundamental (basic), functional unit of life.

• Every living organism is made up of one or more cells: unicellular or multicellular.

• All cells are produced from existing (other) cells i.e pre-existing cells produce new ones through a process called cell division.

Binary fission is an asexual reproduction wherein the body of a prokaryotic organism such as bacterium, is divided into two (2) new identical bodies.

In order to demonstrate that all cells come from pre-existing cells, you should observe a bacterium performing binary fission (dividing) to form clones of itself.

In conclusion, the chromosome (pre-existing cell) of a bacterium containing deoxyribonucleic acid (DNA) and associated proteins replicates and then divides in half to form clones of itself (identical daughter cells).
