Correct Answer: B
Solution :
Polyethylene Glycol (PEG) and sodium nitrate enhances fusion of protoplasts (protoplast fusion). Protoplast fusion is a physical phenomenon which occurs due to the fusion of protoplast (cell without cell wall) of two or more cells. It can be done by mechanically (spontaneous) or inducing agents.(i) Spontaneous agents Mechanical fusion |
(ii) Inducing agents (i) \[NaN{{O}_{3}}\] treatment |
(iii) High pH or \[C{{a}^{2+}}\] treatment |
(iv) PEG treatment |
(v) Electrofusion |
