Question

Statement I : All prokaryotes have a cell wall, eukaryotes do not.
Statement II : Prokaryotes have a true nucleus, eukaryotes have a primitive nucleus.

• A. Both statement I and statement II are true and statement II is the correct explanation of statement I.
• B. Both statement I and statement II are true but statement II is not the correct explanation of statement I.
• C. Statement I is true but statement II is false.
• D. Both statement I and statement II are false.

Answer 1

Answer: (D)

Both statement I and statement II are false.

Prokaryotes generally have a tough layer which helps to maintain the strength and rigidity of the cells known as the cell wall. All the prokaryotes do not possess cell walls such as Mycoplasma. Eukaryotes like animals lack cell walls it starts with plasma membrane while plants have a cell wall.

Prokaryotes have a primitive nucleus that lacks membrane while eukaryotes have a true nucleus that has a double membrane nucleus. Thus, the correct answer is option D.
