The acorn, or oaknut, is the nut of the oaks and their close relatives (genera Quercus and Lithocarpus, in the family Fagaceae). It usually contains a single seed (occasionally two seeds), enclosed in a tough, leathery shell, and borne in a cup-shaped cupule.
Though sometimes referred to mistakenly as an “acorn tree,” the tree that produces acorns is the oak. Different oaks produce acorns of different shapes and sizes, making a tree’s acorns a helpful tool when identifying an oak species.
how long does it take for an acorn to become a tree? If left unmolested, the seedling will gradually grow and develop into a sapling tree after four to five years. The sapling then grows into a small tree that flowers and produces its own acorns. Many oak trees can live for hundreds of years, fruiting new acorns every spring and summer.
Subsequently, one may also ask, can humans eat acorns?
