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?
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?
Options
- AII and III
- BII only
- CII and IV
- DI and III
Correct answer
B. II only
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 correct.
Answer: II only
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 correct.
Answer: II only
