Answer 1

The correct option is D Haberlandt

Totipotency refers to the ability of many cells to retain the full genetic potential characteristic of the mature organism from which any of the cells were obtained, and thus enable the cell to regenerate the organism’s tissues and organs under favorable conditions. The possibility of regenerating an entire plant from a single or few non-zygotic cells was proposed by Gottlieb Haberlandt in 1902. Haberlandt is popularly called the father of tissue culture.

Therefore, the correct answer is option D.
