Question:
Choose the correct statements among the following:
A) As the anthers of Hibiscus is single lobed it will have four microsporangia
B) Pollengrain has two layers wall made up of sporopollenin
C) By maturation and dehydration, Microspores develop into pollengrain
D) Epidermis, endothecium and middle layer will help in dehiscence of anthers
Choose the correct statements among the following:
A) As the anthers of Hibiscus is single lobed it will have four microsporangia
B) Pollengrain has two layers wall made up of sporopollenin
C) By maturation and dehydration, Microspores develop into pollengrain
D) Epidermis, endothecium and middle layer will help in dehiscence of anthers
Show Hint
Sporopollenin is found only in the outer wall (exine) of pollen grains, making them highly resistant to decay.

Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Development and structure of the male gametophyte (pollen) in angiosperms.
Step 2: Meaning
Evaluating: A is false (Hibiscus anthers are monothecous, usually 2 microsporangia). B is false (only exine contains sporopollenin, intine does not). C is true. D is true.
Step 3: Analysis
Statements C and D are biologically accurate processes regarding pollen development and anther dehiscence.
Step 4: Conclusion
The correct combination of statements is C and D.
Final Answer: (D)
