Correct Response: B. The Golgi apparatus is an organelle that helps sort, modify, and transport membrane components and secreted proteins that were made in the endoplasmic reticulum. This function is required in all eukaryotic cells, including both plant and animal cells. Cell walls (A) and central vacuoles (D) are found in plant but not animal cells. Animal cells contain lysosomes, which perform hydrolytic functions for the cell (C). These same functions are performed by vacuoles in plant cells.
