The property of plant cells that helped them to grow into a new plant is totipotency.
The advantages of micropropagation are:
i. It is possible to achieve propagation of a large number of plants in very short durations. Plants like tomato, banana, apple, etc., have been produced on commercial scale.
ii. Healthy plants can be recovered from diseased plants by micropropagation. This is done by removing the meristem, which is disease-free and growing it in vitro. This has been done in banana, sugar cane, potato, etc.
