where do acorns come from

Acorns come from oak trees. They are the nuts or fruit produced by these trees, containing seeds that can grow into new oak trees. Oak trees belong to the genus Quercus, which consists of hundreds of species found worldwide. Acorns develop as a result of fertilized ovules in the oak flowers and take several months (usually between 5 to 24 months, depending on the species) to mature before falling to the ground where they can potentially germinate under the right conditions. Oak trees produce acorns as their method of reproduction, and these acorns serve as an important food source for many animals as well as having been a historically significant food for humans.
