Conifer seeds are produced in tiny scale-like things called seed cones or ovulate cones. These are completely different from the yellow, wormlike, pollen-producing cones you shook next to your car. At pollination time, seed cones are so small and inconspicuous that most people never notice them.
A conifer is a type of tree that produces cones and evergreen needles. Spot a pile of cones beneath a tree and you've found yourself a conifer. With the word cone embedded in it, it's no surprise that conifer is the term used for cone-producing trees. Conifers can often be identified by their typically long needle-shaped leaves like the kind you find on a Christmas tree.
