Question

Quizplus · Accepted Answer

The major difference in the extracellular matrix (ECM) between plant and animal cells is that plant ECM is primarily carbohydrate in nature, whereas animal ECM is largely protein-based. Plant ECM is made up of cellulose, hemicellulose, and pectins, among other carbohydrate-based components. In contrast, animal ECM contains proteins such as collagen, elastin, and fibronectin, as well as carbohydrates like glycosaminoglycans. This difference is due to the distinct physical properties and needs of plant and animal cells.
