Question 10

Stigma, Ovary, and Style are Female Reproductive Parts of a Flower

Stigma, ovary, and style are the three structures that make up the female reproductive part of a flower, known as the pistil. These components work together to facilitate the process of fertilization and the formation of seeds.

A) Stigma

Stigma is indeed a female reproductive part of a flower. It serves as the receptacle for pollen grains during pollination, playing a crucial role in the fertilization process.

B) Ovary

Ovary is also a key component of the female reproductive system in flowers. It houses the ovules, which develop into seeds upon fertilization, making it essential for reproduction.

C) Style

Style is the elongated structure that connects the stigma to the ovary. It supports the stigma and allows pollen tubes to grow from the stigma to the ovary following pollination, confirming its role as a female reproductive part.

D) Petal

Petals are not part of the female reproductive system; instead, they are colorful structures that attract pollinators. While important for the reproductive process, they do not contribute directly to the formation of seeds or ovules.

Conclusion

Stigma, ovary, and style are integral components of the female reproductive system in flowers, facilitating pollination and fertilization. In contrast, petals serve a different function by attracting pollinators and do not participate in reproduction. Thus, the correct answer highlights the essential structures involved in the reproductive process of flowering plants.
