Detailed explanation-1: -(A) In a cell, protoplast consist of the following except cell wall. Explanation: Protoplast is a plant cell and it does not have a cell wall. The protoplast consist of a nucleus, cell membrane and cytoplasm.

Detailed explanation-2: -The protoplasm is the living material of the cell. It is primarily composed of biomolecules like nucleic acids, proteins, lipids, and carbohydrates. It also holds inorganic salts and molecules of water. The protoplasm is surrounded by the membrane of the cells.

Detailed explanation-3: -So, the correct answer is ‘Cell wall’.

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.

Detailed explanation-5: -Protoplasts are somatic plant cells which lack cell walls and are produced by treating plant material (usually the leaf) with cellulase enzyme.
