Question

A plant cell has potential to develop into a full plant. The property is called
A. Tissue culture
B. Pluripotency
C. Totipotency
D. Gene cloning

Answer 1

Hint: Some plant and animal cells have genetic potential to produce the adult fertile organism. We use this potency of plants in tissue culture and vegetative propagation. These cells are called totipotent cells and the property is called totipotency.

Complete answer:
In this question, we have been asked about the property of plants in which a plant cell has potential to develop into a full plant. Some single cells have the ability to divide and produce all the differentiated cells of an organism, it also forms extraembryonic tissues. These cells formed during sexual or asexual reproduction and also form spores and zygotes. In some organisms, cells can dedifferentiate and regain this property. These cells are called totipotent cells and the property is called totipotency. Isolated cells from differentiated tissue are generally non- dividing. These cells undergo dedifferentiation and redifferentiation to express totipotency. We have four options, the first option is tissue culture. Tissue culture is the growth of cells derived from living tissue in an artificial medium and the preparation of cells obtained by tissue culture.The next option is pluripotency. Pluripotent cell refers to a stem cell that has the potential to differentiate into any of the three germ layers only: endoderm, ectoderm and mesoderm. Pluripotent cells cannot make a whole plant. Next option is Totipotency. Totipotency is the ability of a single cell to divide and produce all of the differentiated cells in an organism. The next option is gene cloning. Gene cloning is the process of isolating a desired DNA sequence and making multiple copies of it. The identical copies are clones.

So, the correct option is C. Totipotency.

Note:
In Latin totus means entirely and potency means power. The generation of the whole plant from a non - zygotic cell was proposed by G. Haberlandt. G. Haberlandt is known as the father of tissue culture. Totipotency is the cell with the greatest differentiation potential because it is able to differentiate into any embryonic cell, as well as extraembryonic cells. In contrast, pluripotent cells can only differentiate into embryonic cells.
