Which component connects stigma to ovary in the pistil?

• A. Filiment
• B. Style
• C. Petal
• D. Anther

Answer: (B)

This question tests how a flower’s female reproductive parts are connected and how pollen moves to fertilize ovules. The style is the slender stalk that links the stigma, the surface that receives pollen, to the ovary at the base of the pistil. After pollen lands on the stigma, a pollen tube grows down through the style to reach the ovules in the ovary for fertilization. The other parts belong to different structures: the filament is a stalk that supports the anther in the male part, the anther produces pollen, and petals are part of the flower’s corolla and aren’t involved in connecting stigma to ovary.
