Why do plant cells need cell walls? What is it made up of?

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. ... Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules.

Explanation: brainliest

The cells walls are tough, flexible, and sometimes rigid. And these are perfect for a defense. Plant cells require the cell wall for protection against variations in temperature, high wind speed, atmospheric moisture, among other things. The cell wall is located just outside the cell membrane and it is made up of Cellulose and Peptidoglycan. The “peptide” part of the substance is from short chains of amino acids called peptides. The “glycan” part is long chains of sugars which along with the peptides make up the mesh of the cell wall.
