👉 The term "semicellulose" is a biological and chemical term in plant cell wall that refers to cellulose, which is a type of polymer composed of alternating chains of glucose units. These chains are arranged in a specific pattern, with two or more chains forming a repeating unit known as a celluloside. Semicellulose has been identified in various plant tissues, including the bark and the tracheids (the thin tubes that carry sap from the roots to the leaves)
