Allows the cell to move
D
Where proteins are made
Explanation: 

Detailed explanation-1: -The cell wall surrounds the plasma membrane and provides the cell tensile strength and protection. Besides the presence of chloroplasts, another major difference between plant and animal cells is the presence of a cell wall.

Detailed explanation-2: -A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.

Detailed explanation-3: -The cellulose molecules provide tensile strength to the primary cell wall.

Detailed explanation-4: -The cell wall provides strength and structural support to the cell, and can control to some extent what types and concentrations of molecules enter and leave the cell. The materials that make up the cell wall differ depending on the type of organism.

Detailed explanation-5: -Complete answer: Generally, the cell wall of plants is composed of strong Cellulose but the layer of lignin forms the Secondary cell wall and this is what gives it the strength and rigidity.
