Verified step by step guidance1
Understand the role of each macromolecule in the cell: Polysaccharides, Nucleic Acids, Lipids, and Proteins.
Polysaccharides, such as cellulose in plants and chitin in fungi, provide structural support to cells by forming rigid cell walls.
Nucleic Acids, like DNA and RNA, are primarily involved in storing and transmitting genetic information, not structural support.
Lipids, including phospholipids and cholesterol, are key components of cell membranes but do not primarily provide structural support.
Proteins can provide structural support, such as collagen in connective tissues, but in the context of cellular structure, polysaccharides are more directly involved in forming rigid structures like cell walls.
