In a plant cell, what provides structure, support, and protection to the cell?

In a plant cell, the cell wall provides structure, support, and protection to the cell. The cell wall is a rigid layer that is located outside the cell membrane and surrounds the cell. It is primarily composed of cellulose, a polysaccharide, along with other polysaccharides and proteins. The cell wall helps to maintain the shape of the cell and prevents it from bursting or collapsing under different pressures and forces. It also provides protection against environmental stress and pathogens.

The cell membrane is a thin, flexible layer that surrounds the cytoplasm and regulates the flow of substances in and out of the cell. Cellulose and chitin are components of the cell wall in different types of organisms but not in plants.
