Question: what is the main difference between the two types of cones produced by conifers?
Answer: Conifers have two types of cones: pollen cones and seed cones. Depending on the tree species, you may find both types of cones on the same tree or on different trees. When seed and pollen cones are found on different trees, the species is called dioecious. Female cones have scales under which the ovules are found.
