Acorns are the fruit or nut of an oak tree, and each acorn contains a single seed encased in a tough outer shell. There are hundreds of varieties of oak trees, and each one has a specific and unique type of acorn that it grows. Although there is a great deal of variety in the appearance of leaves, bark, and other features, all types of oak trees grow nuts called acorns. Acorns are a staple food source for many animals, including squirrels, deer, and birds.

Here are some common types of oak trees that produce acorns:

• White Oak Trees: These trees come from the whitish coloring underneath the leaves and typically have rounded tips. They also tend to develop acorns faster than red oak trees.

• Red Oak Trees: These trees get their name from the coloring of their leaves, being deep red and having pointed tips.

• Bur Oak: This tree produces the largest acorns on the continent, about 1.5 inches (4 cm) long with a very deep cupule that covers at least half of the nut.

• Water Oak: This tree produces shallow cup acorns.

If you want to identify oak trees by their acorns, you can look for characteristics such as the size and shape of the nut, the shape and size of the cap, and whether the cap covers the entire nut or just a portion of it.
