Do pinecones release sperm on female pinecones?

Answer 1

Yes and no. The big brown pinecones on the ground that most people consider pinecones are actually female pinecones. The male pinecones are the small pollen structures. Each pollen structure has over a hundred sperm cells, and each pinecone has several egg cells inside it. Not all of them will get fertilized, but in a successful instance, wind or gravity will cause a tiny piece of the pollen, one sperm cell, to fall inside of the female pinecone to fertilize it.

Answer 2

Pinecones are the seed-bearing structures of pine trees, not the reproductive structures. Pine trees produce male cones that release pollen to fertilize female cones, leading to the production of seeds. So pinecones themselves do not release sperm on other pinecones.
