Question

Which one of the following is the true definition of the totipotent cell?
A. An undifferentiated cell is capable of developing into an organ.
B. An undifferentiated cell is 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 are capable of developing into complete embryos.

Answer 1

A cell is the smallest and most fundamental element of life, responsible for all of life's processes.” All living things are made up of cells, which serve as structural, functional, and biological components. A cell can reproduce on its own. As a result, they're dubbed "life's building blocks".

Complete answer:
The cell potential is defined as a cell's ability to develop into other cell types, according to Hans R. Schöler's 2007 book "The Potential of Stem Cells: An Inventory". The stronger a cell's potency, the more cell types it may develop into. Potency is also defined as a cell's gene activation potential, which, as a continuum, starts with totipotency to indicate a cell with the most differentiation potential, then progresses through pluripotency, multipotency, oligopotent, and unipotency.
The capacity of a single cell to proliferate and create all of the differentiated cells in an organism is known as totipotency. Totipotent cells include spores and zygotes, for example. The cell with the greatest differentiation potential, totipotency, can differentiate into any embryonic cell as well as extraembryonic cells, according to the spectrum of cell potency. Pluripotent cells, on the other hand, can only develop into embryonic cells.
Thus, Totipotency is the ability of a single cell, including extraembryonic tissues, to differentiate. Spores and zygotes are totipotent cells that develop during sexual and asexual reproduction. As a result, each totipotent cell is a self-contained entity capable of generating the entire organism.

Thus, the answer is option B: An undifferentiated cell capable of developing into a system or entire plant.

Note:
In cell biology, a unipotent cell is defined as a stem cell that can only develop into one kind of cell. It's still a mystery if real unipotent stem cells exist. Hepatoblasts are bipotent cells that can develop into hepatocytes (which make up the majority of the liver) or cholangiocytes (bile duct epithelial cells). The precursor cell is a near-synonym for unipotent cells.
