Question

The concept of totipotency in plants was given by

• A. Schwan
• B. Morgan
• C. Murashige
• D. Haberlandt

Hint:

• Totipotency (Plant Cells) The inherent capacity of a plant cell to differentiate and regenerate into a whole plant.
• Gottlieb Haberlandt (1902) First to propose the concept of plant cell totipotency and attempt single-cell culture.
• Practical demonstration of totipotency (regeneration of whole plants from cultured cells/tissues) came later by other scientists.

Answer 1

The Correct Option is D

The concept of totipotency in plants was introduced by the German botanist Gottlieb Haberlandt. Totipotency is the ability of a single plant cell to divide and produce all of the differentiated cells in an organism, including the formation of a complete organism. This foundational concept is crucial in the field of plant biotechnology and tissue culture.

Other options provided are:

• Schwan: Known for cell theory but not related to totipotency in plants.
• Morgan: Credited with discoveries in genetics but not associated with totipotency.
• Murashige: Known for his contributions to plant tissue culture media but not for the concept of totipotency.

Therefore, the correct answer is Haberlandt.
