Verified step by step guidance

Identify the primary function of the cell wall in cells. The cell wall is a rigid layer that surrounds the cell membrane in plants, fungi, and certain prokaryotes.

Understand that the cell wall is primarily responsible for providing structural support and protection to the cell. It helps maintain the shape of the cell and prevents it from bursting in hypotonic environments.

Differentiate the cell wall from other cellular structures. Unlike the cell membrane, the cell wall is not involved in regulating the passage of substances into and out of the cell.

Recognize that the cell wall does not store genetic information. This function is typically associated with the nucleus in eukaryotic cells or the nucleoid region in prokaryotic cells.

Acknowledge that the synthesis of proteins is a function of ribosomes, not the cell wall. Ribosomes can be found in the cytoplasm or attached to the endoplasmic reticulum.
