In which structure do angiosperms form their seeds?
Stigma
Ovary
Xylem
Chloroplast
The correct answer is: Ovary
Angiosperms, commonly known as flowering plants, form their seeds in the ovary. The ovary is part of the female reproductive structure of a flower, known as the carpel or pistil. Within the ovary, ovules develop, and after fertilization, these ovules mature into seeds. The process begins when pollen is transferred to the stigma, which leads to fertilization of the ovule within the ovary. Once fertilized, the ovules become seeds, and the ovary often develops into a fruit, which serves to protect the seeds and aid in their dispersal. The stigma is involved in the initial stages of fertilization as the site where pollen lands, but it does not participate in seed formation. Xylem is primarily responsible for water transport and does not play a direct role in seed development. Chloroplasts are organelles involved in photosynthesis and energy production in plant cells and are not related to the reproductive process involved in seed formation.
