Question 5
Which three parts make up the gynoecium?
The right answer is the one marked above.
Stigma, style and ovary. Read from the top down they are a path: the stigma is where pollen lands, the style is what it travels through, and the ovary is where it arrives.
Anther and filament are the two parts of the androecium. Sepals and petals make up the calyx and corolla. Receptacle, style and anther mixes parts from three different whorls, and the receptacle is not in any of them — it is the base the whorls sit on.
