The female gametophyte plant in a flowering plant life cycle is represented by the ______.
Gynoecium
Androecium
Pollen grain with pollen tube
Zygote
Embryo sac with its included nuclei
Embryo sac with its included nuclei.
The female gametophyte plant in a flowering plant life cycle is represented by the Embryo sac with its included nuclei.
The correct answer is "Embryo sac with its included nuclei."
To arrive at this answer, we need to understand the terms and the structure of a flowering plant's life cycle.
The female gametophyte in flowering plants, also known as angiosperms, is represented by the embryo sac. The embryo sac is a structure located within the ovule, which is found within the gynoecium. The gynoecium is the female reproductive part of a flower and is composed of one or more carpels. Each carpel consists of an ovary, style, and stigma. The ovary contains the ovules, and each ovule contains an embryo sac.
The embryo sac is a specialized structure that contains the female gametes (nuclei) necessary for sexual reproduction in plants. It is within the embryo sac that fertilization occurs when a pollen tube from the male gametophyte (pollen grain) delivers the sperms (nuclei) to the egg(s) in the embryo sac. This leads to the formation of a zygote, which eventually develops into an embryo.
Therefore, of the options provided, the correct representation of the female gametophyte plant in the flowering plant life cycle is the "Embryo sac with its included nuclei."
