Answer:

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.
