Question

what is the main function of the cell wall in a plant cell?
to make lipids

to give the cell its fixed shape

to direct cell activities by sending instructions to different parts of the cell

to fill the space between the cell membrane and the nucleus

Explanation:

• "to make lipids": Lipid synthesis is done by the smooth endoplasmic reticulum, not the cell wall.
• "to give the cell its fixed shape": The cell wall in plant cells provides structural support and gives the cell a fixed, rigid shape.
• "to direct cell activities...": This is the function of the nucleus (containing DNA with instructions).
• "to fill the space...": The cytoplasm fills the space between the cell membrane and nucleus, not the cell wall.

Answer:

B. to give the cell its fixed shape
