Question

Which one of the following is the true definition of totipotent cell?

• A. An undifferentiated cell capable of developing into an organ
• B. An undifferentiated cell capable of developing into a system or entire plant
• C. Cells that lack the capability of differentiating into an organ or system
• D. Undifferentiated cells capable of developing into complete embryo

Answer 1

Answer: (B)

An undifferentiated cell capable of developing into a system or entire plant

Totipotency is defined as the ability of a single cell to get differentiated, including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes. Thus, each totipotent cell is a self-contained entity that can give rise to the whole organism.

So, the correct answer is option B.
