Question

Given below are two statements.

Statement I - Microspore is covered by two layered covering called sporoderm.

Statement II - Sporopollenin is not present in the region of germ pores in microspore.

In the light of above statements, Select the correct option given below:

• A. Both statement I and statement II are correct.
• B. Both statement I and statement II are incorrect.
• C. Statement I is correct but statement II is incorrect.
• D. Statement I is incorrect but statement II is correct.

Hint:

Recall the sporoderm layers and where sporopollenin is absent.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept
A microspore (pollen grain) is covered by a two-layered sporoderm: the outer exine and the inner intine.
Statement I is correct.

Step 2: Key Point
The exine is made of sporopollenin, which is very resistant.
It is absent at certain places called germ pores, where the pollen tube emerges.
Statement II is correct.

Step 3: Compare the options
Both statements are correct.

Final Answer:
Both statements are correct. \[ \boxed{\text{(A) }\text{Both statement I and statement II are correct.}} \]
