Q. Cellular totipotency is demonstrated by

A) All eukaryotic cells
B) Only bacterial cells
C) Only gymnosperm cells
D) All plant cells
Explanation

Professor F C Steward of Cornell University (USA) demonstrated that mature cells removed from a carrot and placed in a suitable culture solution could be stimulated to start dividing again and to provide new carrot plants (totipotency). Totipotency is inherent capability of a single cell, which provides the genetic programme required to direct the development of an entire individual.
