Which of the following are extracellular carbohydrate structures?

Extracellular carbohydrate structures are materials outside the cell that are built largely from polysaccharides or carbohydrate-rich matrices. Cell walls are classic exterior features in plants, bacteria, and fungi, made from cellulose or other polysaccharides that give rigidity and protection. Exoskeletons in many arthropods use chitin, a long carbohydrate polymer, as a tough external layer. Cartilage is an extracellular matrix in animal tissues that contains proteoglycans with long carbohydrate chains (glycosaminoglycans), which gives it its gel-like, resilient properties. In contrast, mitochondria, nuclei, and chromosomes are housed inside cells and are not extracellular carbohydrate structures. So that set of structures accurately identifies extracellular carbohydrate components.
