Biology of Plants

What does the word "pollination"
mean?

Pollination is the transfer of pollen from a stamen to a pistil. Pollination starts the production of seeds.

What about plants that
don't have flowers?
 
Some plants don't have flowers. Plants such as
mosses and ferns reproduce by spores. Cone-bearing plants, like pine or spruce trees for example, reproduce by means of pollen that is produced by a male cone and travels by wind to a female cone of the same species. The seeds then develop in the female cone.
