Solution
Protoplasts are used for genetic engineering because do not have cell walls.
Explanation:
A protoplast has had its cell wall removed, making it easier to introduce foreign DNA or fuse it with another protoplast. Its cytoplasm is not inert, and protoplasts retain a cell membrane; having a diploid nucleus is not the reason.
