Question

which statement differentiates plant cells from animal cells?

• ribosomes found on the er function in the production of proteins for the cell.
• cell membranes maintain the shape and control the flow of materials into and out of the cell.
• cell walls composed of cellulose provide structure and support.
• cytoplasm allows nutrients and raw materials to move throughout the cell.

Explanation:

To differentiate plant and animal cells, we analyze each option:

• Ribosomes on ER making proteins: Occurs in both plant and animal cells.
• Cell membranes maintaining shape/regulating flow: Both cell types have cell membranes with this function.
• Cell walls of cellulose: Plant cells have cell walls (animal cells do not), so this is a key difference.
• Cytoplasm moving materials: Both plant and animal cells have cytoplasm with this role.

Answer:

C. Cell walls composed of cellulose provide structure and support.
