Question

What is totipotency of a cell?

Answer 1

Totipotency:

1. Totipotency is defined as having the ability to develop into any of its cells or tissues or to become a complete creature.
2. Totipotency, which includes extraembryonic tissues, is the capacity of a single cell to proliferate and give rise to all differentiated cells in an organism.
3. Spores and zygotes are examples of totipotent cells produced during sexual and asexual reproduction.
4. Cells can dedifferentiate and regain totipotency in some organisms.
5. One can grow a full plant from a plant cutting or callus, for instance.
6. When a sperm fertilizes an egg, the resulting zygote, a single-celled embryo, begins the process of developing into a mammal.
