Here's why:

* Cones: Conifers have cones, which are specialized structures for reproduction.

* Pollen: Male cones release pollen, which is light and dry.

* Wind dispersal: The wind carries the pollen to female cones on other trees.

* No insects: Conifers don't rely on insects for pollination.

This is different from many flowering plants, which rely on insects or animals to transfer pollen. Wind pollination is a less efficient process, but it's well-suited for conifers that grow in vast forests where insect pollination might not be reliable.
