Detailed explanation-4: -Protoplast refers to a cell that doesn’t possess a cell wall. Protoplast is comprised of the plasma membrane, cytoplasm, and cell organelles. The cell wall can be removed the certain enzymes such as cellulase and pectinase. Protoplasts are commonly used for research purposes.
