Question

The inherent capacity of a cell to regenerate a new whole organism is called [Kerala CET 2003]
A) Ontogeny
B) Totipotency
C) Phycogeny
D) Differentiation

Answer 1

Answer:

A)Ontogeny

Ontogeny (also ontogenesis or morphogenesis) is the origination and development of an organism, usually from the time of fertilization of the egg to the organism's mature form—although the term can be used to refer to the study of the entirety of an organism's lifespan.

Answer 2

Answer:

The correct answer is B) Totipotency

Explanation:

Totipotency is the ability of a cell to differentiate into all the type of cell that an adult organism is made up of that means a totipotent cell can give rise to a whole organism through regeneration.

Zygotes are the example of a totipotent cell in animals that can give rise to the whole organism. Spores of different fungus and algae are also the example of totipotent cell and some plant part can be used to generate whole plant in favorable condition which is also the example of totipotent cell.

Therefore the inherent capacity of a cell to regenerate a new whole organism is called totipotency.
