Protoplast are the cells devoid of
A
Cell membrane
B
Cell wall
C
Both of the above
D
None of the above
Explanation: 

Detailed explanation-1: -Protoplasts are cells which have had their cell wall removed, usually by digestion with enzymes. Cellulase digests the cellulose in plant cell walls while pectinase breaks down the pectin holding cells together. Once the cell wall has been removed, the resulting protoplast attains a spherical shape.

Detailed explanation-2: -Protoplasts are somatic plant cells which lack cell walls and are produced by treating plant material (usually the leaf) with cellulase enzyme.

Detailed explanation-3: -Protoplasts of plant cells consist of ordinary plant cells devoid of their largely polysaccharide cell wall.

Detailed explanation-4: -Sclerenchyma cells are dead cells and they are devoid of protoplasm.

Detailed explanation-5: -Definition. A protoplast is a bacterial, fungal, or plant cell that has had its cell wall completely or partially removed using either enzymatic or mechanical means. Cell walls are made of a variety of polysaccharides (peptidoglycan, chitin, cellulose).
