Dear student,
Yes, it is scientifically possible to grow thousands of the plant from a single cell of that same plant. The technique is known as micropropagation. The property which plays a major role in the growth of the thousands of the plant from that plant cell is called as totipotency. In micropropagation, the cell culture techniques are performed in the laboratory to grow a large number of the plants from the single cell. The plants produced are of the same type and are also called as the somaclones and the method is called as the clonal propagation.
