Not all plants need to make seeds. Ferns and mosses for example do not have to produce seeds to spread.
Any plant that has a flower as part of it's reproductive system has pollen as part of that process.
only if pollen has landed on the stigma and the pollen tube is growing down the style
Yes, To set seed, which is the purpose of the flower, the flower must be pollinated by some means.
both angiosperms and gymnosperms produce pollen
The same way as all other plants - pollen. Some species release their pollen into the wind, some need insects to spread it from tree to tree. Some trees produce nuts, some produce seeds. All use pollen.
No. They release pollen, but do not do so through flowers. Fir trees do have flowers but they are insignificant.
Trees emit pollen as a means to procreate.
Cedar trees are wind pollinated. They release vast amounts of pollen into the atmosphere. it is caught by wind currents and eventually lands on a different cedar tree.
Dates are produced on Date Palm Trees. They have Male and Female forms. The Male trees produce Pollen. They pollen fertilizes the female trees which produce the dates. Commercial groves grow only a few male trees. They take the pollen from them and fertilize the female flowers by hand. Most palms use the wind to spread their pollen but spreading pollen by hand makes fewer male trees necessary. That way more female trees can be grown and more dates produced.
The pollen is to produce acorns, which produce more oak trees.
No, they are male trees and only produce pollen
No, not as such, though trees have cells which perform the same purpose in the form of pollen.
