Sap is the thick, sticky fluid that is inside tree branches and stems. You can't see it until the plant is damaged in some way, like having a branch cut off or some kind of insect bores a hole into it. Many kinds of sap are sweet and are eaten by birds and insects. People collect the sap from maple trees to make maple syrup. Latex is made from sap as well.
