What is the anatomy of a flower provide a brief explanation of the structures involved in pollination and fertilization

A flower has the following:

Petals - segments of the flower

Sepal - outer parts of the flower at the bottom covered in bud

Stamen - produces pollen in the flower

Anther - where pollen is produced

Pistil - produces ovary of the flower

Stigma - where pollen germinates

Pollination occurs when insects like bees and butterflies transfers the pollen from one flower to another. Once transferred, fertilization begins.
