function and importance;

2..A major role of the cell wall is to form a framework for the cell to prevent over expansion. Cellulose fibers, structural proteins, and other polysaccharides help to maintain the shape and form of the cell. Additional functions of the cell wall include: Support: The cell wall provides mechanical strength and support

in the absence of cell wall;

If cell wall is absent in plant cell then all the functioning of all the cell organelles present inside the cell would be affected as diffusion of various substances would not occur. The cell membrane provides several vital functions for the cell. Cell walls anchor the cytoplasm and hold the cell's shape.
