This structure provides additional support and protection to plant cells.
A
Cell Wall
B
Cell Membrane
C
Cytoplasm
D
Pellicle Membrane
Explanation: 

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

Detailed explanation-2: -In plants, cell wall provides both structural support and protection.

Detailed explanation-3: -Cellulose in the cell wall is organized into strong beams called microfibrils. Cellulose microfibrils function as the backbone of the cell wall (Figure 1C). Pectin, the concrete of the plant cell wall, is more flexible than cellulose, and it allows the cell wall to extend.

Detailed explanation-4: -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-5: -The Plant Cell Wall: A Complex and Dynamic Structure As Revealed by the Responses of Genes under Stress Conditions. The plant cell wall has a diversity of functions. It provides a structural framework to support plant growth and acts as the first line of defense when the plant encounters pathogens.
