Correct Answer: B
Solution :
[b] Mycoplasma cells are bacteria without walls. Plasmid is a genetic structure in a cell that can replicate independently of thechromosomes. It is typically a small circular DNA strand in the cytoplasm of a bacterium or protozoan are sac- like membranes that make up grana in a chloroplast. Lysosomes are a single membrane bound vesicular structure. It contains many hydrolytic enzymes and commonly called as suicidal bag of the cells. It is involved in intracellular and extracellular digestion.
