The capacity to generate a whole plant from any cell of the plant is called:
The inherent capacity of any single plant cell / explant to regenerate into an entire plant is called Totipotency!
Plant tissue culture is based on the cellular phenomenon that whole plants can be regenerated from explants (any part of a plant taken out and grown in a test tube under sterile conditions in a special nutrient medium).
This capacity to generate a whole plant from any cell or explant is termed totipotency, first experimentally demonstrated by Gottlieb Haberlandt and perfected by F.C. Steward using carrot phloem explants.
Diagnose every choice: Know exactly why the right option works and why distractors fail.
Micropropagation is the commercial in vitro method of producing thousands of plants from explants.
Differentiation is the biochemical and structural specialization of a cell into a mature cell type.
Totipotency is the intrinsic biological ability of a single plant cell to regenerate an entire multicellular plant.
Somaclonal variation refers to genetic or epigenetic mutations arising during cell culture.
Confusing the cellular property (totipotency) with the technological process (micropropagation).
"This capacity to generate a whole plant from any cell/explant is called totipotency. You will learn how to accomplish this in higher classes."
