The cell wall of most bacteria is primarily composed of peptidoglycan, a polymer consisting of sugars and amino acids, which provides structural support and protection. Statement 2 is incorrect. Fungal cell walls are mainly composed of chitin, a tough polysaccharide, although other components like glucans are also present. Plant cell walls are made of cellulose. Statement 3 is correct. Animal cells do not possess a rigid cell wall. Instead, animal tissues have an extracellular matrix (ECM) which is a complex network of secreted molecules, including various proteins (like collagen, elastin) and glycoproteins (like proteoglycans, which are composed of protein and carbohydrate chains), providing support, adhesion, and signaling functions.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nThe presence or absence and composition of the cell wall are key distinguishing features between different kingdoms of life.
