Below is the picture with labelled structure. (Pic from Landcare Research website).

Produce pollen grains: Anther.

Anther is the male reproductive system of the flower. And pollen grains carries the genetic information of the male.

Pollen grains lands: Stigma

Stigma is a part of the female of the flower. It is usually large and sticky depending on the pollen grains' travelling agent (wind/insects). It is like that so that more pollen grains can land on the stigma.

Fertilisation occurs: Ovary

Ovary is the location where the nucleus of ovule from the female and the nucleus of the pollen grain from male fuse together. This process is called fertilisation. After fertilisation, a zygote is produced, and it'll soon develop into an embryo and to a fruit.

Pollen tube travels down: Style

The style is also a part of the female system. When the pollen grains land on the stigma, pollen tubes are produced under sugary solutions. The pollen tube containing the nucleus of the male gamete is travelled down to the ovary for fertilisation through the style.

Attracts pollinators: petals

Petals are usually large and colourful in order to attract pollinators, usually insects in this case. As the insects come towards the petals, pollen grains may stick to them so that the pollen grains containing male nucleus can be carried to the female part.
