Question

The ability of an isolated cell to produce whole plant is called as

• A. Totipotency
• B. Differentiation
• C. Homeostasis
• D. Dedifferentiation

Answer 1

The correct option is A Totipotency

Totipotency is the ability of a single cell to divide and produce all of the differentiated cells in an organism. Spores and zygotes are examples of totipotent cells. In the spectrum of cell potency, totipotency represents the cell with the greatest differentiation potential. Many somatic plant cells, including some fully differentiated types (e.g., leaf mesophyll), provided they contain intact nuclear, plastid and mitochondrial genomes, have the capacity to regenerate into whole plants.

Differentiation is the process by which a cell changes from one cell type to another. Most commonly this is a less specialized type becoming a more specialized type, such as during cell growth.

Homeostasis is the property of homeostasis within the human body. The human body manages a multitude of highly complex interactions to maintain balance or return systems to functioning within a normal range.

Dedifferentiation is an important biological phenomenon, whereby cells regress from a specialized function to a simpler state reminiscent of stem cells.

Thus, the correct answer is option A.
