SSC MTS 2023 PYQ — Question 77

The correct answer is option 2 i.e. It provides shape and rigidity to the cell.

The major function of a cell wall is to provide structural support and protection to the cell. It gives the cell its shape, protects against mechanical stress, and prevents excessive intake of water, thereby preventing cell lysis. In plants, the cell wall is primarily composed of cellulose, hemicellulose, and pectin, which contribute to its rigidity and strength. Additionally, the cell wall acts as a barrier to pathogens and plays a role in cell-to-cell communication.
