Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Engineered cells of some plants like petunias, tobacco, and tomatoes can readily be used to regenerate entire plants under sterile conditions. For this to take place the the cells must return to an ____ state.

A	asexual
B	undifferentiated
C	dormate
D	cellular

Explanation:

Detailed explanation-1: -Alternatively, a small piece of plant somatic tissue-an explant-can reproduce a new tissue or growth structure not present before injury. In “cell totipotency, ” an entire plant can even be regenerated from a single somatic cell (Haberlandt, 1902).

Detailed explanation-2: -Any viable plant cell can differentiate into somatic embryos.

Detailed explanation-3: -White (1939a) defined a plant tissue culture as a system in which cells satisfied two main requirements of remaining “undifferentiated yet capable of unlimited growth” (White, 1939a).

Detailed explanation-4: -Gottlieb Haberlandt: In plants, totipotency of excised plant tissues and cells was established subsequently. It was Gottlieb Haberlandt, an Austrian scientist, who conceived the idea of culturing isolated plant cells in the nutrient solutions.
