it evolved in response to dry land environments
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
Seeds have evolved to facilitate reproduction and dispersal of plant species. They are the result of the fusion of male and female gametes (sperm and egg) and contain an embryo and nutrient reserves enclosed in a protective seed coat. This allows seeds to be dispersed, germinate, and develop into new plants in diverse environments.
Pollen
birds carry pollen and spread seeds
No, they do not. They reproduce by budding. Pollen is produced by flowering plants.

pollen joins an ovule to make seeds

seeds
the seeds and embryos and pollen
A flower produce pollen sacs which has pollen grains in it
Pollen
The ovary in the flower must be fertilised by pollen from the stamen and then seeds can form.
Conifer trees have two different kinds of cones. The pollen cones house the male reproductive cells. They produce pollen which is later transferred to the female cone to fertilize the seeds. The seed cone houses the female reproductive cells, which when pollinated become seeds.
plants with seeds evolved from simpler plants which evolved from single celled organisms
the answer is pollen
