Question

Which of the following is responsible for the formation of androecium?

• A. Stamen
• B. Pollen
• C. Pollen sac
• D. Style

Hint:

The androecium is the collective term for the stamens of a flower, which are responsible for producing pollen.

Answer 1

The Correct Option is A

Step 1: Understand the concept of androecium.
Androecium is the male reproductive organ of a flower, which consists of stamens. Each stamen includes an anther and filament.
Step 2: Analyze the options.
- Stamen: The stamen is responsible for producing pollen, which is the male gametophyte, and thus forms the androecium. - Pollen: Pollen is produced by the anther of the stamen, but it is not the structure responsible for forming the androecium. - Pollen sac: The pollen sac is a part of the anther, where pollen grains develop, but it does not directly form the androecium. - Style: The style is part of the female reproductive organ (pistil) and does not form the androecium.
Step 3: Conclusion.
The stamen is the structure that forms the androecium, so the correct answer is (A).
Final Answer: \[ \boxed{Stamen} \]
