Step-by-step solution
Somatic hybridisation involves the fusion of protoplasts of two different plant varieties to produce a hybrid plant.
The correct sequence of steps is as follows:
First, single cells are isolated from two different varieties of plants (Step D).
Next, the cell walls of these isolated cells are digested using enzymes such as cellulase and pectinase (Step A).
This digestion results in the isolation of naked protoplasts, which are cells without cell walls (Step B).
The isolated naked protoplasts from the two different varieties are then fused together, often using chemicals like PEG or electrical stimulation, to get a hybrid protoplast (Step C).
Finally, the hybrid protoplast is cultured and grown to form a new plant (Step E).
Thus, the correct sequence is D, A, B, C, E.
Answer: D, A, B, C, E
The correct sequence of steps is as follows:
First, single cells are isolated from two different varieties of plants (Step D).

The isolated naked protoplasts from the two different varieties are then fused together, often using chemicals like PEG or electrical stimulation, to get a hybrid protoplast (Step C).
Finally, the hybrid protoplast is cultured and grown to form a new plant (Step E).
Thus, the correct sequence is D, A, B, C, E.
