What type of tree is known for producing acorns?

The type of tree known for producing acorns is the oak tree. Acorns are the nuts produced by oak trees and serve as a vital source of food for various wildlife, including squirrels, birds, and other animals. The reproductive cycle of oak trees includes the flowering of male and female parts, eventually leading to the formation of the acorn, which contains the seed.

While maples, pines, and firs are also tree species, they do not produce acorns. Maples produce seeds known as samaras, pines generate cones that contain seeds, and firs also produce cones, but none of these are classified as acorns, which are uniquely associated with oaks. Thus, the oak is the only tree amongst the options provided that is specifically recognized for its acorn production.
