Question

which of the following does not correctly match the organelle with its function?
cytoskeleton helps maintain the cells shape.
the cell membrane regulates what enters and leaves the cell.
ribosomes make proteins that are needed by the cell.
lysosomes help transport materials throughout the cell.

Explanation:

• Cytoskeleton: It is a network of protein filaments in the cell. Its main functions include maintaining cell shape, enabling cell movement, and facilitating intracellular transport. So, the description "Cytoskeleton helps maintain the cell's shape" is correct.
• Cell membrane: It is a selectively - permeable membrane. It regulates the entry and exit of substances into and out of the cell. So, the description "The cell membrane regulates what enters and leaves the cell" is correct.
• Ribosomes: These are the sites of protein synthesis in the cell. They use mRNA as a template to assemble amino acids into proteins that are needed by the cell. So, the description "Ribosomes make proteins that are needed by the cell" is correct.
• Lysosomes: These are organelles that contain digestive enzymes. Their main function is to break down waste materials, cellular debris, and foreign substances (such as pathogens) within the cell. Vesicles (such as endosomes and transport vesicles) are responsible for transporting materials throughout the cell. So, the description "Lysosomes help transport materials throughout the cell" is incorrect.

Answer:

Lysosomes help transport materials throughout the cell.
