A flower can generate an embryo through self-fertilization. What statement best describes the process of self-fertilization in the flower?
A.
An egg produced by the ovary falls onto the anther, causing pollen on the anther to project a pollen tube. When the tube reaches the egg, the male gamete fertilizes the egg, which then falls to the petal.
B.
Pollen produced by the anther falls on the stigma, and projects a pollen tube that grows through the style. The pollen tube pierces an ovule in the ovary, and the male gamete fertilizes the egg of the ovule.
C.
An egg produced by the filament falls onto the stigma, and then travels down the style to the ovary. A male gamete from pollen in the ovary fertilizes the egg.
D.
Pollen produced by the stigma falls on the anther. The pollen travels down the filament until it reaches an ovule in the ovary, where the male gamete is fertilized.
