What part of the female part of the flower is a tube that pollen travels through?
A
Ovary
B
Style
C
Filament
D
Stigma
Explanation: 

Detailed explanation-1: -The female part is the pistil. The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style.

Detailed explanation-2: -pistil, the female reproductive part of a flower. The pistil, centrally located, typically consists of a swollen base, the ovary, which contains the potential seeds, or ovules; a stalk, or style, arising from the ovary; and a pollen-receptive tip, the stigma, variously shaped and often sticky.

Detailed explanation-3: -During the pollination process of higher plants, after the pollen germinates on the stigmatic surface, a pollen tube is formed from the pollen and extends down the style into the ovule; nuclei from the pollen travels through the pollen tube to fertilize the ovule.

Detailed explanation-4: -The style is the tube-like structure that holds up the stigma. The style leads down to the ovary that contains the ovules. Other parts of the flower that are important are the petals and sepals.

Detailed explanation-5: -The female elements are collectively called the pistil. The top of the pistil is called the stigma, which is a sticky surface receptive to pollen. The bottom of the pistil contains the ovary and the narrowed region in between is called the style.
