The outer support and protective structure of a plant cell is the  cell wall. All plant cells have an outer cell wall composed of  cellulose or lignin. Edit. Share to: Answered. In Biology.
The cell wall is a tough, flexible and sometimes rigid layer that surrounds some types of cells. It surrounds the cell membrane and provides these cells with structural support and protection. In addition, the cell wall acts as a filtering mechanism.A major function of the cell wall is to act as a pressure vessel, preventing over-expansion when water enters the cell. Cell walls are found in plants, fungi and prokaryotic cells but not in mycoplasmas. The secondary cell wall, a thick layer formed inside the primary cell wall after the cell is fully grown. 2  It is not found in all cell types. 3  Some cells, such as the conducting cells in xylem, possess a secondary wall containing lignin, which strengthens and waterproofs the wall.
