Consider the following statements in respect of cell and its structure: I. All cells possess cell wall. II. All cells have ribosomes present inside. III. All cells have well-organized nucleus. IV. All cells have linear DNA molecules present in them. Which of the statements given above is/are correct?

Step-by-step solution

Statement I is incorrect because animal cells and mycoplasma do not possess a cell wall. Statement II is correct because ribosomes are non-membrane bound organelles found in all living cells, both prokaryotic and eukaryotic. Statement III is incorrect because prokaryotic cells lack a well-organized nucleus and membrane-bound organelles. Statement IV is incorrect because prokaryotic cells typically contain circular DNA, whereas eukaryotic cells contain linear DNA in their nucleus. Therefore, only statement II is cor
