Question

Given below are two statements:
Assertion (A): Prokaryotic cells are larger and may remain similar in shape and size.
Reason (R): The organisation of prokaryotic cells are similar eventhough they exhibit a wide variety of shapes and functions.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Prokaryotic cells are generally smaller and simpler than eukaryotic cells.

Answer 1

The Correct Option is D

Concept:
Prokaryotic cells are simple cells without a true nucleus and membrane-bound organelles.

Step 1: Check Assertion.
The assertion says that prokaryotic cells are larger. This is incorrect because prokaryotic cells are generally smaller than eukaryotic cells. \[ A \text{ is incorrect} \]

Step 2: Check Reason.
The basic organisation of prokaryotic cells is similar. They have plasma membrane, cytoplasm, ribosomes and genetic material, although they may show different shapes and functions. \[ R \text{ is correct} \]

Step 3: Final conclusion.
Assertion is incorrect, but Reason is correct. \[ \therefore \text{Correct Answer is (D)} \]
