Which of the following is NOT a part of a flower?

Petiole

The correct answer is Option (2)-Petiole

The correct answer is "Petiole."

Explanation:

• Petiole is a part of the leaf structure, not the flower.
• It is a slender stalk that attaches the leaf blade to the stem.
• In contrast, stamen, sepal, and pistil are all parts of the flower structure.
• Stamen is the male reproductive organ of the flower, consisting of an anther and a filament.
• Sepal is the outermost whorl of the flower, typically green in color, and protects the flower bud.
• Pistil, also known as the carpel, is the female reproductive organ of the flower, consisting of the stigma, style, and ovary.
