Flowers reproduce using pollination and fertilization. Put the steps of these processes in order. Start with the first step of pollination, and end with the last step of fertilization.
i) A seed is formed.
ii) A grain of pollen combines with an ovule.
iii) Pollinators land on a flower and some pollen gets stuck on the stigma.
iv) A pollen tube grows down the style.
v) Pollinators land on a flower and pick up pollen on their bodies.

Starting with the first step of pollination, the process of reproduction in a flower is as mentioned below:

v) Pollinators land on a flower and pick up pollen on their bodies.

iii) Pollinators land on a flower and some pollen gets stuck on the stigma.

iv) A pollen tube grows down the style.

ii) A grain of pollen combines with an ovule.

i) A seed is formed.

Extra information:

Pollination is the transfer of male gametes onto the female gametes, while fertilization is the fusion of these two gametes. It is the process in which the nuclei of the female gamete and male gamete unite together in the ovary of the flower to form a diploid zygote.  Pollination is the process where pollen grains are transferred from the male anther of a flower to the female stigma, for the fertilization and production of seeds. 

Different types of pollination are self-pollination and cross-pollination.

Self-Pollination - This type of pollination occurs when the pollen of one flower transfers to the stigma of the same flower or another flower of the same plant.

Cross-Pollination - This type of pollination occurs when the pollen of one flower transfers to the stigma of another flower of different plants of the same species.

Pollination is done either by biotic agents like insects, birds, and bats or by abiotic agents like wind and water.
