Answer:
Short answer-False
Explanation:
Answer;
-Cell wall
Explanation;
-The cell wall is thick and fibrous and provides a barrier between the cell and its external environment.
-The plant cell wall is composed of cellulose. Cellulose is a structural carbohydrate and is considered a complex sugar because it is used in both protection and structure. The plant cell wall consists of three layers. Each layer has its own unique structure and function.
-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.
Cell wall supports and maintains the cell's shape and protects the cell from damage (option B)'
The plant cell is protected by a layer called the cell wall, which encloses the cell membrane. This rigid structure, composed of cellulose offers both support and safeguarding functions, for the cell. Additionally the cell wall plays a role, in preserving the cells shape and preventing it from rupturing when exposed to pressure.
The cell membrane on the hand forms an outer layer encompassing every type of cell.
