Question

Tissue culture technique was first attempted by
A. Haberlandt
B. Hanning
C. Nobecourt
D. Gautheret

Answer 1

Hint: Tissue culture is also known as micropropagation and in this technique fragments from an animal or plant are transferred to a culture medium where they can continue to live and function.

Complete answer:
First of all, you should know what tissue culture is. Tissue culture is a method in which the fragments from an animal or plant are transferred to an artificial environment where there is development of the plant under controlled condition.
 This artificial environment is made with a nutrient culture medium of known composition and there these fragments are transferred.
The culture tissue may consist of a single cell, multiple cells or a whole organ and the plant which get developed by the tissue culture is then cloned and the technique is called micropropagation. Gottlieb Haberlandt was the first scientist to attempt this tissue culture technique.
If we look at options now, Option A is Haberlandt. It is the correct option as he is known as the father of tissue culture and he was the first to attempt tissue culture technique. Therefore, this option is correct.
Moving to option B which is Hanning. It is an incorrect option because Hanning did not discover tissue culture technique but Haberlandt was the first scientist who attempted tissue culture technique. Therefore, this option gets eliminated.
Moving to option C which is Nobecourt. He also attempted tissue culture technique but in the question, the first person is asked who attempted tissue culture technique and Haberlandt was first to attempt this technique. Therefore, this option is incorrect and it gets eliminated.
Last option D is Gautheret. This option is also incorrect because in the question, the first person is asked who attempted tissue culture technique and Haberlandt was first to attempt this technique not Gautheret. Therefore, this option is incorrect and it gets eliminated.

Thus, the correct answer is option A which is Haberlandt.

Note:
This technique is used to maintain plant cells or tissue under sterile conditions as there is artificial growth of these tissues by taking fragments from an animal or plant which is then transferred to a nutrient culture medium of known composition. This technique was first attempted by Gottlieb Haberlandt.
