Homonym: bark (Sound)
Bark is the outer covering of a tree, acting like a protective shield. It helps keep the tree safe from insects, diseases, and harsh weather. Just like our skin protects our bodies, bark plays a crucial role in the health of trees. Different types of trees have different kinds of bark, which can be smooth, rough, thick, or thin.
In addition to protection, bark also helps transport nutrients and water within the tree. The inner layer of bark, called the phloem, carries food made by the leaves down to the roots. This process is essential for the growth and survival of trees like oak and maple.
