d. it holds the cell in its proper position
The plant cell wall is one of the important parts of a plant cell. It is considered to be the protective layer or gear of a plant cell located outside the cell membrane which supports the cell's structure. It is the main factor that affects the plant's actual shape. It also helps in determining what elements can only come in the plant cell in order to control or to prevent the destruction or the damage of the cell or the plant itself. It serves as a gatekeeper or even a strainer that strains out harmful elements away from the cell.
