Plant Cell: Cell Wall Structure

What is the primary function of the cell wall in a plant cell?

• Regulation of cell division

• Structural support and protection

• Energy production

• Storage of genetic material

Describe the composition of the cell wall in a plant cell.

• Cellulose, hemicellulose, pectin, and lignin

• Chitin, cellulose, and pectin

• Lipids, amino acids, and water

• Protein, starch, and sugar

How does the structure of the cell wall differ from the cell membrane?

• The cell wall is flexible and regulates what enters and exits the cell, while the cell membrane is rigid and provides structural support.

• The cell wall and cell membrane have the same structure and function.

• The cell wall is only found in animal cells, while the cell membrane is only found in plant cells.

• The cell wall is rigid and provides structural support, while the cell membrane is flexible and regulates what enters and exits the cell.

Explain the role of the cell wall in providing support to the plant cell.

• It helps in photosynthesis in the plant cell.

• It regulates the movement of materials in and out of the plant cell.

• It provides structural support to the plant cell.

• It stores water and nutrients in the plant cell.

What are the different layers of the cell wall and their functions?

• Primary cell wall, secondary cell wall, and middle lamella with their respective functions.

• Outer cell wall, inner cell wall, and middle layer with their respective functions.

• Primary layer, secondary layer, and tertiary layer with their respective functions.

• Cell membrane, cytoplasm, and nucleus with their respective functions.
