What is the uppermost part of the pistil, female reproductive tissue of a flower?

• A. Pistil
• B. Style
• C. Flower stigma
• D. Anther

Answer: (C)

Stigma is the uppermost part of the pistil, serving as the pollen-receptive surface. The pistil as a whole is the female reproductive structure and includes three parts: the stigma at the top, the style beneath it, and the ovary at the base. The stigma’s role is to catch pollen; once pollen lands there, it germinates and grows a pollen tube down the style toward the ovary for fertilization. The style is simply the stalk connecting stigma to the ovary, while the anther is part of the male reproductive organ (stamen) and produces pollen. So the stigma is located at the very top of the pistil and is specialized for receiving pollen.
