Which of the following is the correct sequence for the pollen tube to eventually reach the egg in a flowering plant? a. stigma, style, ovary, ovule b. style, stigma, ovary, ovule c. stigma, ovary, ovule, style d. ovary, ovule, stigma, style
The stigma functions as a receptive surface on which pollen lands and germinates its pollen tube. Corn silk is part stigma, part style. The style serves to move the stigma some distance from the ovary. This distance is species specific.
OVARY
The Ovary
The ovary contains one or more ovules, which in turn contain one female gametophyte, also referred to in angiosperms as the embryo sac. Some plants, such as cherry, have only a single ovary which produces two ovules. Only one ovule will develop into a seed.
