Most angiosperms have vessels in their xylem. The Anthophyta is divided into just two classes, monocots and dicots. Ovules are enclosed by a carpel, which is morphologically a megasporophyll. Pollen is transferred not directly to the ovule, but to the stigma of the carpel. The pollen tube grows through stigma and style to ovary where it enters an ovule through the micropyle.
Double fertilization occurs.
As ovule matures into the seed, the carpel matures into the fruit.
