Question

New cells are generated from

(a) Bacterial fermentation

(b) Regeneration of old cells

(c) Pre-existing cells

(d) Abiotic materials

Answer 1

New cells generate from the pre-existing cells.

The cell theory is a widely accepted explanation of the relationship between cells and living things. The cell theory states :

• All living things or organisms are made of cells.

• New cells are created by old cells dividing into two.

• Cells are the basic building units of life.

In 1858, Rudolf Virchow concluded that all cells come from pre-existing cells, thus completing the classical cell theory.
