Pollen cones are the male pollen-producing cones, and seed cones are the female seed-producing cones in conifer trees.Seed cones are gymnosperms, which means the seeds are not enclosed within an ovary (in Greek, gymno is naked).
pollen joins an ovule to make seeds
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
Spores are single-celled reproductive structures produced by fungi and some plants, while pollen is a fine powder produced by flowering plants for reproduction. Dandelions are flowering plants that produce pollen as part of their reproductive process, and they also have a distinct fluffy structure that disperses their seeds.
seeds
the seeds and embryos and pollen
A flower produce pollen sacs which has pollen grains in it
one makes seeds and another does not make seeds

The difference between an Angiosperm and a Gymnosperm is that Angiosperms are flowering plants while Gymnosperms are not. A. include plants that use flowers to reproduce. More information on this topic can be researched online or in a biology book. I strongly recommend Dale Layman's Biology Demystified for more info. An angiosperm also forms seeds inside a protective chamber called an ovary and a gymnosperm bears naked seeds (no ovary).
These terms relate to plants. Pollination means that pollen is transferred to a second plant to fertilize it and produce seeds. The seeds are later planted and a new individual is germinated (grown) from the seed. This is like the egg and sperm producing a zygote which will grow into a new animal.
The ovary in the flower must be fertilised by pollen from the stamen and then seeds can form.
