The Correct Option is C
Solution and Explanation
Step 1: Understanding protoplasts.
- Protoplasts are plant cells with the cell wall removed, leaving only the plasma membrane and cytoplasm.
Step 2: Concept of somatic hybridization.
- Somatic hybridization is a technique to fuse two different plant protoplasts to form a hybrid cell.
- This hybrid can regenerate into a hybrid plant combining traits of both parent plants.
Step 3: Procedure.
- Protoplast isolation from donor plants.
- Fusion of protoplasts using chemical (PEG) or electrical methods.
- Culture of hybrid protoplasts in nutrient medium to regenerate a hybrid plant.
Step 4: Applications.
- Combines desirable traits from two different species or varieties.
- Useful in overcoming sexual incompatibility barriers.
Step 5: Comparison with other options.
- Cloning: producing genetically identical copies of a plant.
- Mutation: creating variations through changes in DNA.
- Fusion: general term; not specific to somatic hybridization.
Step 6: Conclusion.
Hence, the process is called Somatic hybridization.
- Protoplasts are plant cells with the cell wall removed, leaving only the plasma membrane and cytoplasm.
